Biology Question on respiration in plants
In aerobic respiration, total number of ATP molecules formed from 1 glucose molecule is
A
28
B
32
C
36
D
30
Answer
36
Explanation
Solution
The net gain from complete oxidation of a glucose molecule in aerobic respiration is 36 ATP molecules. 10 molecules of NADH (2 from Glycolysis + 8 from Krebs??cycle) yield = 10 ??3 = 30 ATP, 2 molecules of FADH yield = 2 ??2 = 4 ATP and glycolysis also yields 2 ATP. Therefore, total release of ATP per hexose will be = 30 + 4 + 2 = 36 ATP.
