Question

Net yield aerobic respiration during Kreb's cycle per glucose molecule is

• A. 2 ATP molecules
• B. 8 ATP molecules
• C. 36 ATP molecules
• D. 38 ATP molecules

Answer 1

Answer: (D)

38 ATP molecules

38 ATP molecules are formed during Kreb's cycle per glucose molecule.

In glycolysis, 4 ATPs are formed, bt 2 ATPs are used. so net ATPs formed are 2. In acetylation, 2 NADPH2 are formed, I.e. 6 ATPs are formed ( 1 NADPH2 = 3 ATPs ) in the Kreb cycle. 30 ATPs are formed.

SO NET ATPs FORMED ARE 38.....
