Question

In aerobic respiration. How many ATPs are synthesised when 1)One molecule of glucose is oxidised? 2)one molecule of NADH is oxidised? 3)one molecules of FADH is oxidised? I

Answer 1

In aerobic respiration how many ATPs are synthesised when ?

• one molecule of glucose is oxidised :- 38 ATP

EXPLANATION :-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 NADH2 in the mitochondria

• One molecule of NADH is oxidised :- 3 ATP

EXPLANATION :- Oxidation of one molecule of NADH gives rise to 3 molecules of ATP, while that of one molecule of FADH2 produces 2 molecules of ATP.

• One molecule of FADH2 is oxidised :- 2 ATP

EXPLANATION :- one molecule of FADH2 produces 2 molecules of ATP.
