How many ATP are produced in cellular respiration?

Answer 1

During the process of aerobic respiration as many as 38 molecules of ATP are produced for every molecule of glucose that is utilized. Thus aerobic respiration process breaks down a single glucose molecule to yield 38 units of the energy storing ATP molecules. However, it takes 2 ATP to start the process. A net 36 are produced.

• priming glycolysis

+4

• substrate level phosphorylation (glycolysis)

+6

• 2 NADH produced (glycolysis)

-2

• transportation of two NADH into mitochondria

+6

• 2 NADH produced in conversion of pyruvate to acetyl-CoA

+18

• 6 NADH produced during Kreb's cycle

+4

• 2 2"FADH2 produced during Kreb's cycle

+2

• substrate level phosphorylation (Kreb's cycle)

+36

• total ATPs produced from one glucose from aerobic respiration in eucaryotes. Compare with total from glycolysis alone (i.e., 2 ATP).

one glucose molecule gives 36 ATPs on its oxidation in cellular respiration

Answer 3

38 ATP are produced in the whole cellular respiration because in the

KREBS CYCLE = 2 ATP were produced

GLYCOLYSIS = 2 ATP were also produced

ELECTRON TRANSPORT CHAIN = 34 ATP

Answer 4

Approximately 36-38 ATP molecules are typically produced in cellular respiration from the complete oxidation of one molecule of glucose. This ATP is generated through the processes of glycolysis, the citric acid cycle, and oxidative phosphorylation in the mitochondria.

Answer 5

38 The equation for cellular respiration is:

C6H12O6 + 6O2 = 6H2O + 6O2 + 38ATP

Answer 6

30 ATP's

30-40 ATP's

Answer 7

36 ATP molecules are produced by cellular respiration.
