It is a process of converting water and carbon dioxide to glucose and oxygen in the presence of sunlight and chlorophyll. It is a process by which bacteria produces carbohydrates, sulfur and water. The presence of sunlight is necessary.

What organisms use chemosynthesis?

Prokaryotic microorganisms, principally bacteria and archaea (referred to as “bacteria” in the following), carry out chemosynthetic reactions. Energy is produced in chemosynthetic reactions from oxidizing reduced compounds.

Where does the energy come from in chemosynthesis?

Chemosynthesis is the conversion of carbon (usually carbon dioxide or methane) into organic matter using inorganic molecules (hydrogen or hydrogen sulfide) or methane as an energy source. Most energy is initially derived from sunlight via plant photosynthesis.

What plants use 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 are the effects of chemosynthesis?

In general, chemosynthesis has received less attention than the associated energy-yielding redox processes, which drive many biogeochemical cycles and have profound impacts on the production and cycling of greenhouse gases such as carbon dioxide, methane, and nitrous oxide.

What is the most likely explanation for anoxic chemosynthesis?

The most likely explanation for anoxic chemosynthesis is that electron acceptors other than O 2 are being used deeper in the anaerobic water column.

What is the process of producing organic compounds from C-1 compounds?

Chemosynthesis. Chemosynthesis can be defined as the biological production of organic compounds from C-1 compounds and nutrients, using the energy generated by the oxidation of inorganic (e.g., hydrogen gas, hydrogen sulfide, ammonium) or C-1 organic (e.g., methane, methanol) molecules. From: Encyclopedia of Inland Waters, 2009.

Is chemosynthesis in lakes or streams?

Chemosynthesis by bacteria is normally very low in the pelagic of streams, infertile waters, and lakes of intermediate productivity and becomes a significant contribution to the whole only in productive or meromictic lakes exhibiting steep redox gradients.

Is chemosynthesis most extensive during stratification?

Water column studies indicate that chemosynthesis is most extensive during stratification. In sediments overlain with oxic water, redox gradients are likely to be permanently present, although the oxygen penetration and consequently the depth of the redox interfaces may vary over time.

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 ...

Who discovered chemosynthesis?

Cavanaugh later managed to confirm that this was indeed the method by which the worms could thrive, and is generally credited with the discovery of chemosynthesis. A 2004 television series hosted by Bill Nye named chemosynthesis as one of the 100 greatest scientific discoveries of all time.

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.

Which organisms obtain carbon from carbon dioxide?

Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse. Groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic iron-oxidizing bacteria .

Is chemosynthesis a synonym of chemoautotrophy?

Thus, chemosynthesis can be seen as a synonym of chemoautotrophy . The term " chemotrophy ", less restrictive, would be introduced in the 1940s by André Lwoff for the production of energy by the oxidation of electron donors, organic or not, associated with auto- or heterotrophy.

Energy for Life

What was the last meal you ate? Any idea what it did for your body? Chances are that meal provided your body with the energy necessary for life. All living things on Earth need energy in order to survive. However, how life forms obtain their energy various. People obtain this energy by consuming other organisms, such as with your last meal.

Chemosynthesis in Nature

Found deep within the ocean are structures known as hydrothermal vents. These vents produce a seemingly toxic compound, known as hydrogen sulfide. I say 'seemingly' because hydrogen sulfide is toxic to humans, but not to all life. In fact, living amidst the hydrothermal vents are organisms called giant tube worms.

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 chemo used for?

More often, chemo is used with surgery or radiation therapy or both. And it's sometimes used with other drugs, such as targeted therapy, hormone therapy, or immunotherapy. For example, chemo may be used... To shrink a tumor before surgery or radiation therapy. Chemo used in this way is called neoadjuvant therapy.

Why do people need chemo?

When the cancer is at an advanced stage, probably cannot be controlled, and has spread, the goal of giving chemo may be to improve the quality of life or help the person feel better. For instance, chemo may be used to help shrink a tumor that’s causing pain or pressure so the patient feels better and has less pain.

How often is chemo given?

Chemotherapy is commonly given at regular intervals called cycles. A cycle may be a dose of one or more drugs on one or more days, followed by several days or weeks without treatment. This gives normal cells time to recover from drug side effects. Sometimes, doses may be given a certain number of days in a row, or every other day for several days, followed by a period of rest. Some drugs work best when given continuously over a set number of days.

What is the term for the use of drugs to treat cancer?

Chemotherapy refers to the use of any drug to treat any disease. But to most people, the word chemotherapy ( or "chemo") means drugs used for cancer treatment. It's important to know that not all medicines and drugs to treat cancer work the same way. It used to be that the only kind of drug that could treat cancer was traditional or standard chemo, ...

What is the term for the process of shrinking a tumor?
