What is the relationship between oxygen and ATP?
What is the relationship between oxygen and ATP?
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.
What is the relationship between energy ATP and cellular respiration?
Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
What happens if oxygen is absent during cellular respiration?
When oxygen is not present and cellular respiration cannot take place, a special anaerobic respiration called fermentation occurs. Fermentation starts with glycolysis to capture some of the energy stored in glucose into ATP. Some bacteria carry out lactic acid fermentation and are used to make products such as yogurt.
What would happen to cellular ATP synthesis in the absence of oxygen?
ATP stands for adenosine triphosphate and is the energy source used by cells. The production of ATP is much greater in the presence of oxygen. In the presence of oxygen, 34-38 ATP are produced per glucose molecule. In the absence of oxygen, the net yield of ATP produced is 2 per glucose molecule.
Why is oxygen important for ATP production?
Why oxygen? Oxygen is the final electron acceptor at the end of the electron transport chain of aerobic respiration. In the absence of oxygen, only a few ATP are produced from glucose. In the presence of oxygen, many more ATP are made.
Is oxygen needed for ATP production?
In aerobic respiration, oxygen is required. Oxygen as a high-energy molecule increases ATP production from 4 ATP molecules to about 30 ATP molecules. In anaerobic respiration, oxygen is not required. When oxygen is absent, the generation of ATP continues through fermentation.
Where is the oxygen used in cellular respiration?
Oxygen is the final electron acceptor of the electron transport chain in the final step of cellular respiration. Oxygen combines with electrons and hydrogen ions to produce water.
What is produced during cellular respiration?
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
What are the three ways in which you can measure the rate of cellular respiration?
There are three ways to measure the rate of cellular respiration. These three ways are by measuring the consumption of oxygen gas, by measuring the production of carbon dioxide, or by measuring the release of energy during cellular respiration. In order to measure the gases, the general gas law must be understood.
What does cellular respiration always release?
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
What stage of cellular respiration produces the most ATP?
Krebs cycle
How do you get 38 ATP from glucose?
There is a theoretical maximum of 38 ATP produced from a single glucose molecule: 2 NADH produced in glycolysis (3 ATP each) + 8 NADH produced in Krebs cycle (3 ATP each) + 2 FADH2 produced I don’t know where (2 ATP each) + 2 ATP produced in the Krebs cycle + 2 ATP produced in glycolysis = 6 + 24 + 4 + 2 + 2 = 38 ATP.
Where do the 36 ATP come from?
Total ATP production from aerobic respiration: 36 ATPs for each glucose that enters glycolysis (2 from glycolysis, 2 from citric acid cycle, 32 from ETP).
