Question

Assertion: Glycolysis is the only process in aerobic respiration.
Reason: It is partial oxidation of glucose that occurs in the cytoplasm of the cell of all living organisms.

• A. Both assertion and reason are correct statements and reason is the correct explanation
• B. Both assertion and reason are correct statements but the reason is incorrect explanation
• C. Assertion is an incorrect statement but the reason is the correct statement
• D. Both are incorrect statements

Answer 1

The correct option is C Assertion is an incorrect statement but the reason is the correct statement

Glycolysis is a pathway in which the breakdown of glucose to pyruvic acid occurs. It results in partial oxidation of glucose. It occurs in both aerobic and anaerobic organisms. It takes place in the cytoplasm of all living cells.

Aerobic respiration occurs in the presence of oxygen. It includes glycolysis, the conversion of pyruvate into acetyl CoA by pyruvate dehydrogenase, followed by subsequent yielding of carbon dioxide, NADH, FADH${}_2$, ATP by Krebs cycle and electron transport chain. Hence, the assertion is incorrect.
