Assertion : During aerobic respiration, pyruvic acid formed as a result of glycolysis, undergoes phosphorylation reaction to form acetyl CoA.
Reason : There is net gain of 18 ATP molecules during aerobic respiration of one molecule of glucose.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Answer

d

Explanation

During aerobic respiration, the final product of glycolysis, i.e. pyruvic acid is transported from the cytoplasm into mitochondria and undergoes oxidative decarboxylation reaction to form acetyl CoA. Aerobic respiration is the complete oxidation of glucose into `CO_(2)` and `H_(2)O`. There can be a net gain of 36 ATP molecules in aerobic respiration of one molecule of glucose.
