Biology Question on respiration in plants
How many ATP molecules produced by Aerobic oxidation of one molecule of glucose : -
A
2
B
4
C
36
D
38
Answer
38
Explanation
Solution
Energy gain in one complete cycle of aerobic respiration.In aerobic respiration complete oxidation of one glucose molecule produces 38 ATP molecules. But the i number of ATP molecules so produced may vary depending upon the mode of entry of NADH in the mitochondria.If the electrons of NADH are accepted by malate then each molecule of NADH yields 3 ATP molecules and the total would be 38 ATP molecules. But if the electrons of NADH are accepted by FAD it yields only 2 ATP molecules making the total of 36 ATP molecules. This type of shuttle occurs in most of the eukaryotic cells.
