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.

# ATP

step

-2

• 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

38 The equation for cellular respiration is:

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

Answer 5

30 ATP's

Krebs Cycle

8 ATP's (possible)

ETC & Glycolysis

1 NADPH

2 NADH

4 NADH (2)

1 FADHR

1 ATP (2)

30-40 ATP's

Answer 6

36 ATP molecules are produced by cellular respiration.
