The net gain of energy from one gram mole of glucose during aerobic respiration is

A

2 ATP

B

36 ATP

C

38 ATP

D

15 ATP

Text Solution

Verified by Experts

The correct Answer is:
C

ATP molecules produced during respiration
(1) Glycolysis
Direct – 2molecules of ATP
2 molecules of `NAD_2H = 6` molecules of ATP
(One molecule of `NADH_2` yield 3 ATP )
(2) Pyruvic acid to acetylCOA
2 molecules of `NADH_2 = 6` molecules of ATP
(3) Citric acid cycle
`6NADH_2 ` = 18 molecules of ATP
`2FADH_2 ` = 4 molecules of ATP
2GTP = 2 molecules of ATP
Total net gain of ATP = 38 ATP
