What do chemosynthetic organisms produce?

Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways.

Does chemosynthesis produce oxygen?

Instead of releasing oxygen gas while fixing carbon dioxide as in photosynthesis, hydrogen sulfide chemosynthesis produces solid globules of sulfur in the process.

Does chemosynthesis produce energy?

Instead of sunlight being the primary form of energy, chemical energy is produced by a process called chemosynthesis. Places with chemosynthetic organisms, such as hydrothermal vents, can become incredible oases of life in the deep sea.

What does chemosynthesis and photosynthesis produce?

Chemosynthesis exploits chemical energy to convert inorganic carbon compounds into organic matter, in contrast with photosynthesis, which exploits the energy of light to produce organic matter.

Does chemosynthesis produce ATP?

Like photosynthesis and cellular respiration, chemosynthesis uses an electron transport chain to synthesize ATP.

Does chemosynthesis produce carbon?

Chemosynthesis☆⁎⁎⁎ Chemosynthesis is defined as the biological production of organic compounds from one-carbon (C-1) compounds and nutrients using the energy generated by the oxidation of inorganic or C-1 organic molecules.

What happens in chemosynthesis quizlet?

What happens during chemosynthesis? one or more carbon molecules (usually carbon dioxide or methane, CH4) and nutrients is converted into organic matter, using the oxidation of inorganic molecules (such as hydrogen gas, hydrogen sulfide (H2S) or ammonia (NH3)) or methane as a source of energy, rather than sunlight.

How do chemosynthetic organisms make energy?

Chemosynthetic bacteria get their energy through chemosynthesis, a process by which organisms use inorganic molecules to make food and ultimately get energy. For example, chemosynthetic bacteria living in deep sea vents take carbon dioxide and hydrogen sulfide to create glucose, water and sulfur gas.

What plants produce chemosynthesis?

Algae, phytoplankton, and some bacteria also perform photosynthesis. Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis. Autotrophs that perform chemosynthesis do not use energy from the sun to produce food.

What does photosynthesis produce?

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

What are the end products of photosynthesis?

During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

Does photosynthesis or chemosynthesis produce oxygen?

Photosynthetic organisms produce oxygen as a byproduct. Organisms that use chemosynthesis make food energy by using inorganic chemicals and inorganic carbon molecules from their environment. Organisms that use chemosynthesis produce sulfur and sulfur compounds as a byproduct.

Is oxygen required for chemosynthetic organisms?

Chemosynthesis is a process by which food is produced without oxygen and sunlight in places such as dark caves and methane clathrates. In this process, the only raw material that chemosynthetic organisms and plants want is inorganic elements, such as methane and sulfur.

Do chemosynthetic bacteria require oxygen?

Like photosynthetic bacteria, chemosynthetic bacteria need a carbon source (e.g. carbon dioxide) as well as an energy source in order to manufacture their own food. For the most part, these bacteria are aerobic and therefore rely on oxygen to complete this process successfully.

What produces oxygen in the ocean?

oceanic planktonAt least half of Earth's oxygen comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize. One particular species, Prochlorococcus, is the smallest photosynthetic organism on Earth.

How does chemosynthesis produce biomass?

Many microorganisms in dark regions of the oceans use chemosynthesis to produce biomass from single carbon molecules. Two categories can be distinguished. In the rare sites where hydrogen molecules (H 2) are available, the energy available from the reaction between CO 2 and H 2 (leading to production of methane, CH 4) can be large enough to drive the production of biomass. Alternatively, in most oceanic environments, energy for chemosynthesis derives from reactions in which substances such as hydrogen sulfide or ammonia are oxidized. This may occur with or without the presence of oxygen.

What is chemosynthesis in biochemistry?

In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using ...

What is the reaction that produces sulfur?

Some reactions produce sulfur: Instead of releasing oxygen gas while fixing carbon dioxide as in photosynthesis, hydrogen sulfide chemosynthesis produces solid globules of sulfur in the process. In bacteria capable of chemoautotrophy (a form a chemosynthesis), such as purple sulfur bacteria, yellow globules of sulfur are present and visible in ...

What is the process of a giant tube worm?

Hydrogen sulfide chemosynthesis process. Giant tube worms use bacteria in their trophosome to fix carbon dioxide (using hydrogen sulfide as an electron and oxygen or nitrate as an energy source) and produce sugars and amino acids. Some reactions produce sulfur: hydrogen sulfide chemosynthesis: 18 H2S + 6CO 2 + 3 O2 → C 6H12 O 6 ( carbohydrate) ...

What is the term for the production of energy by oxidation of inorganic substances?

In 1897, Wilhelm Pfeffer coined the term "chemosynthesis" for the energy production by oxidation of inorganic substances, in association with autotrophic carbon dioxide assimilation—what would be named today as chemolithoautotrophy. Later, the term would be expanded to include also chemoorganoautotrophs, which are organisms that use organic energy substrates in order to assimilate carbon dioxide. Thus, chemosynthesis can be seen as a synonym of chemoautotrophy .

How do bacteria synthesize methane?

The bacteria synthesize methane by combining hydrogen and carbon dioxide.

Where can animals be supported by chemosynthesis?

Large populations of animals can be supported by chemosynthetic secondary production at hydrothermal vents, methane clathrates, cold seeps, whale falls, and isolated cave water . It has been hypothesized that anaerobic chemosynthesis may support life below the surface of Mars, Jupiter's moon Europa, and other planets.

How does chemosynthesis work?

Chemosynthesis is one of a few main metabolic processes that organisms undertake to obtain food and energy. Chemosynthesis is the biological process by which chemical energy is converted into carbohydrates for the organism's food. Unlike photosynthesis, chemosynthesis can occur in the absence of sunlight, which is why biologists theorize that life may have begun as chemosynthetic bacteria near underwater volcanic vents. Photosynthesis is a metabolic process where an organism converts sunlight, carbon dioxide, and water into glucose and oxygen. This process occurs in plants and in some forms of bacteria. All organisms do another biological process called cellular respiration where glucose and oxygen yield carbon dioxide, water, and energy.

What is Chemosynthesis?

There are three main biological processes or metabolisms that allow organisms to fulfill their internal biological functions: photosynthesis, cellular respiration, and chemosynthesis.

What is the process of converting chemical energy into carbohydrates and glucose?

The textbook chemosynthesis definition is a biological process by which organisms convert chemical energy into the carbohydrates and glucose the organism needs for food. Chemosynthe tic organisms typically exist in ecosystems that are absent of sunlight. For example, many chemosynthe tic organisms are found deep in the ocean and aphotic zones.

How do organisms perform chemosynthesis?

Overall, chemosynthetic organisms convert one or more molecules that contain carbon into organic macromolecules using the oxidation of inorganic compounds as their source of energy. The carbon-containing molecules can be carbon dioxide or methane gas, and the inorganic compounds are often hydrogen gas, hydrogen sulfide, or ferrous ions (iron-containing compounds). In these chemical reactions, the inorganic compounds are oxidized or stripped of some of their electrons, creating ions that allow for the ionic bonding of these compounds. For example, here is the chemosynthesis equation involving hydrogen sulfide:

How many molecules of hydrogen sulfide are introduced to carbon dioxide?

In the above equation, 18 molecules of hydrogen sulfide are introduced to 6 carbon dioxide molecules and 3 oxygen molecules. The inorganic hydrogen sulfide gets oxidized, loses its sulfur atoms, and combines with the carbon and oxygen to yield 1 molecule of glucose, 12 water molecules, and 18 sulfur atoms.

How do plants produce food?

Plants perform photosynthesis to produce their own food during the day by converting solar energy, carbon dioxide, and water into oxygen and glucose or sugar used by the plant. Cellular respiration is the reverse of this process, in which glucose and oxygen are converted into carbon dioxide, water, and energy.

What is the process of producing food in the absence of sunlight?

Organisms that produce their own food in the absence of sunlight perform chemosynthesis, in which the chemical energy of compounds like carbon dioxide and hydrogen sulfide react to oxygen, producing the carbohydrates needed by the organism and other compounds as a byproduct.

Where are chemosynthetic communities found?

Since then, chemosynthetic bacterial communities have been found in hot springs on land and on the seafloor around hydrothermal vents, cold seeps, whale carcasses, and sunken ships. No one had ever thought to look for them, but these communities were there all along.

What is the energy used in photosynthesis?

All photosynthetic organisms use solar energy to turn carbon dioxide and water into sugar (food) and oxygen: 6CO 2 + 6H 2 O -> C 6 H 12 O 6 + 6O 2. Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food.

How do organisms make food?

The majority of life on the planet is based on a food chain which revolves around sunlight, as plants make food via photosynthesis. However, in environments where there is no sunlight and thus no plants, organisms instead rely on primary production through a process called chemosynthesis, which runs on chemical energy. Together, photosynthesis and chemosynthesis fuel all life on Earth.
