So, oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule.
Which stage produces the most ATP?
The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
Which stage of glucose metabolism produces the most energy?
Clearly, with two ATP from glycolysis, two from the citric acid cycle and 34 from the electron transport chain per molecule of glucose, the electron transport chain is by far the most energy-producing.
Which type of metabolism is the most efficient at generating ATP?
Aerobic respiration requires oxygen in order to generate energy ( ATP ). Aerobic metabolism is up to 15 times more efficient than anaerobic metabolism (which yields two molecules ATP per one molecule glucose).
What process produces large amounts of ATP?
Cellular respiration is the process by which biological fuels are oxidised in the presence of a high-energy inorganic electron acceptor (such as oxygen) to produce large amounts of energy, to drive the bulk production of ATP.
Which energy system produces the most ATP?
The aerobic system produces far more ATP than either of the other energy systems but it produces the ATP much more slowly, therefore it cannot fuel intense exercise that demands the fast production of ATP.
Which stage produces Fadh₂?
During the citric acid cycle ATP and molecules called ‘NADH’ and ‘FADH₂’ are produced. NADH and FADH₂ are electron carrying molecules and are important for transporting electrons from the citric acid cycle to the electron transport chain in the final stage of respiration.
Which step of metabolism releases the most ATP?
Glycolysis takes place in the cytoplasm, whereas the Krebs cycle and the electron transport chain, which generate the largest amounts of ATP during cellular respiration, take place in the mitochondria.
Does photosynthesis break down glucose?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. … In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process. Carbon dioxide and water are products of this reaction.
Can glucose be broken down without oxygen?
Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules.
What type of metabolism occurs in the absence of oxygen?
Anaerobic respiration is a type of respiration where oxygen is not used; instead, organic or inorganic molecules are used as final electron acceptors.
Why do we use 36 ATP instead of 38?
During citric acid cycle, 36 ATP molecules are produced. So, all together there are 38 molecules of ATP produced in aerobic respiration and 2 ATP are formed outside the mitochondria. Thus, option A is correct.
What Cannot be metabolised anaerobically?
A molecule of glucose can only produce three ATP molecules under anaerobic metabolism, while it produces 39 with aerobic metabolism. ATP is what fuels the muscles. Anaerobic metabolism can only use glucose and glycogen, while aerobic metabolism can also break down fats and protein.
What are two ways in which ATP is produced in the cells?
The two ATP-producing processes can be viewed as glycolysis (the anaerobic part) followed by aerobic respiration (the oxygen-requiring part).
What are the three ways to make ATP?
The three processes of ATP production include glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation.
What are two ways to make ATP?
There are two methods of producing ATP: aerobic and anaerobic. In aerobic respiration, oxygen is required. Oxygen as a high-energy molecule increases ATP production from 4 ATP molecules to about 30 ATP molecules.
