how many atp are produced in aerobic respiration

Explanation: Out of 36 ATP molecules 2 are produced in glycolysis outside mitochondria and the rest of the ATP molecules are produced inside mitochondria in the Krebs cycle and electron transport chain (respiratory chain).
How many ATP are produced in aerobic respiration quizlet?
In aerobic respiration oxygen (O2) is needed and in anaerobic respiration no oxygen needed. Aerobic produces 36 ATP; Anaerobic produces 2 ATP.
Why is ATP 38 or 36?
In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.
Does aerobic respiration produce 36 or 38 ATP?
ATP yield during aerobic respiration is not 36–38, but only about 30–32 ATP molecules / 1 molecule of glucose .
How are 38 molecules of ATP produced?
The TCA (Tri Carboxylic Acid) cycle or citric acid cycle will occur inside the inner mitochondrial membrane. -During the complete process of aerobic respiration the total number of ATP molecules produced are 38. This process occurs through the breakdown of one molecule of glucose.
How is 34 ATP produced in the electron transport chain?
34 ATP molecules are produced in the electron transport chain if we consider that one molecule of NADH produces 3 molecules of ATP and one molecule of FADH2 gives rise to 2 molecules of ATP.
How do we get 32 ATP?
In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.
How many ATP are produced in total?
Theoretically, 38 ATP molecules can be produced by the complete oxidation of one glucose molecule in aerobic respiration.
How many ATP molecules are produced in aerobic respiration How many ATP molecules are produced during fermentation and glycolysis?
Because oxygen is required for aerobic respiration, it is linked to hydrogen ions to form water. ETP causes the production of 32 ATPs. A total of 36 ATPs are produced from aerobic respiration for each glucose that enters glycolysis (2 from glycolysis, 2 from citric acid cycle, 32 from ETP).
How is 36 ATP produced in cellular respiration?
Electron transport from the molecules of NADH and FADH2 made from glycolysis, the transformation of pyruvate, and the Krebs cycle creates as many as 32 more ATP molecules. Therefore, a total of up to 36 molecules of ATP can be made from just one molecule of glucose in the process of cellular respiration.
How does aerobic respiration produce 38 ATP?
Advantages of Aerobic Respiration
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.
Why is the total count about 30 or 32?
Why is the total count about 30 or 32 ATP molecules rather than a specific number? -It is not a specifc number because when NAD+ becomes NADH in glycolysis, they enter the membrane and can become FADH2. If FADH2 comes acros the membrane 32 ATP are created because each NADH creates 2.5 ATP.
Does anaerobic respiration produce 36 ATP?
Anaerobic cell respiration (glycolysis + fermentation) produces 2 ATP/glucose consumed. Aerobic cell respiration (glycolysis + the Krebs cycle + respiratory electron transport) produces 36 ATP/glucose consumed. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration.
How do you get 38 ATP from glucose?
If glucose is the respiratory substrate, then we get the net gain of 38 ATP molecules in aerobic respiration from one glucose molecule. ATP molecules are produced by substrate-level phosphorylation and oxidative phosphorylation in ETS by the oxidation of NADH and FADH2.
