What is the process by which cells use oxygen and release carbon dioxide?
cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
What is the process of oxygen to carbon dioxide?
This process is called photosynthesis. Carbon dioxide is produced through the respiration of animals and plants, which consume oxygen and release carbon dioxide.
What process in the cell produces carbon dioxide?
Cellular respirationCellular respiration is an oxidative process whereby an electron donor is oxidized and oxygen is reduced to produce carbon dioxide, water, and energy [3].
What are the processes that take place in a cell in the presence of oxygen?
Answer and Explanation: Cellular respiration takes place in the presence of oxygen and this process is also known as aerobic respiration. This process takes place in the mitochondria. The cellular respiration occurs in three stages, these are glycolysis, the Krebs cycle and the electron transport chain.
What is the process of cellular respiration?
Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP . Generally speaking, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
What are the 3 processes of respiration?
There are three main steps of cellular respiration: glycolysis; the citric acid (TCA) or the Krebs cycle; and the electron transport chain, where oxidative phosphorylation occurs. The TCA cycle and oxidative phosphorylation require oxygen, while glycolysis can occur in anaerobic conditions.
Which organism takes in carbon dioxide and gives of oxygen?
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Which process or processes return carbon to the atmosphere?
These are the reservoirs, or sinks, through which carbon cycles. Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.
During which phase of cellular respiration is carbon dioxide released?
the citric acid cycleAnswer and Explanation: The stage of cellular respiration in which carbon dioxide release takes place is the citric acid cycle. Aerobic cellular respiration has three steps, glycolysis, the citric acid cycle and the electron transport chain.
How is CO2 released in cellular respiration?
Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
Where does cellular respiration release CO2?
the mitochondrial matrixCitric acid cycle. The acetyl CoA combines with a four-carbon molecule and goes through a cycle of reactions, ultimately regenerating the four-carbon starting molecule. ATP (or, in some cases, GTP), NADH, and FADH_2 are made, and carbon dioxide is released. These reactions take place in the mitochondrial matrix.
What is aerobic respiration and anaerobic respiration?
Aerobic and anaerobic respiration Living organisms use energy released by respiration for their life processes. There are two types of respiration – aerobic (which needs oxygen) and anaerobic (which doesn't need oxygen). Biology (Single Science) Respiration and gas exchange.
Where does the process of respiration occur?
While most aerobic respiration (with oxygen) takes place in the cell's mitochondria, and anaerobic respiration (without oxygen) takes place within the cell's cytoplasm.
What is the difference between photosynthesis and respiration?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Why is cellular respiration called respiration?
Cellular respiration works either in the presence or absence of oxygen. But essentially, the process is called cellular respiration because the cell seems to “respire” in a way that it takes in molecular oxygen (as an electron acceptor) and releases carbon dioxide (as an end product).
Why do cells do respiration or fermentation?
Cellular respiration and fermentation produce energy for cells to use. Any chemical process that yields energy is known as a catabolic pathway. For nearly all organisms on Earth (except chemolithotrophs), that energy is stored in organic molecules.
In which stage is carbon dioxide released and you get rid of it by exhaling?
Cellular respiration is the process in which the cells of all living things break down the organic compound glucose with oxygen to produce carbon dioxide and water. Oxygen is brought into the body with each inhalation, and carbon dioxide is released with each exhalation.
What are 2 types of respiration?
There are two types of cellular respiration (see Cellular Respiration concept): aerobic and anaerobic. One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic).
What is respiration short answer?
1 : the act or process of breathing : the inhaling of oxygen and the exhaling of carbon dioxide. 2 : the process by which cells use oxygen to break down sugar and obtain energy.
What is ATP in biology?
Adenosine 5′-triphosphate, abbreviated ATP and usually expressed without the 5′-, is an important “energy molecule” found in all life forms. Specifically, it is a coenzyme that works with enzymes such as ATP triphosphatase to transfer energy to cells by releasing its phosphate groups.
Which is the correct pathway of oxygen to the lungs?
When you inhale through your nose or mouth, air travels down your pharynx (back of your throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into two air passages called bronchial tubes. One bronchial tube leads to your left lung, the other to your right lung.
What is the equation of photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What is breathing or external respiration?
External respiration, also known as breathing, involves both bringing air into the lungs (inhalation) and releasing air to the atmosphere (exhalation). During internal respiration, oxygen and carbon dioxide are exchanged between the cells and blood vessels.
What happens during the first step of photosynthesis?
The first process of this process is to entrap light. This step occurs as light reactions that involve photophosphorylation reactions involving photosystems I and II. The entrapped light is used in the formation of energy such as ATP and NADH. This energy is used to process various biosynthesis reactions.
What is the second step of cellular respiration?from quizlet.com
second step of cellular respiration, the pryuvate molecule crosses into the mitochondria where it enters a series of chemical reactions called the "krebs cycle", produces two molecules of ATP and carbon dioxide
What is the chemical reaction that occurs when food combines with oxygen in the cells and releases energy?from quizlet.com
CELLULAR STAGE: chemical reaction that occurs when food combines with oxygen in the cells and releases energy
How does respiration differ from cellular respiration?from quizlet.com
Respiration differs from cellular respiration because respiration is the release of energy from glucose or another organic chemical and cellular respiration the process that occurs when the chemical energy of "food" molecules, carbohydrates, fats, and proteins is released
What happens if a human runs out of oxygen?from quizlet.com
if a human runs out of oxygen fermentation will give the human energy
Where does the body get its sugar from?from healthfully.com
Your body gets its sugar supply from the carbohydrate-containing foods and drinks that you consume. This is because carbohydrates are converted into sugars during the process of digestion. Carbohydrates are found in a variety of food items, including fruits, nonstarchy vegetables, starchy vegetables, beans, lentils, milk, bread, pasta, cereal, rice and nuts. Carbohydrates are also found in processed foods that contain added sugars such as desserts, baked goods and candy.
Why do cells use ATP?from quizlet.com
