Which step in respiration directly produces the most ATP?

Practice MCQ for SSC, UPSC, RRB Exams

A. Glycolysis A.

B. Krebs cycle B.

C. Electron transport chain C.

D. Fermentation D.

Correct Answer: C সঠিক উত্তর: C

Explanation ব্যাখ্যা

In aerobic respiration, the complete oxidation of one glucose molecule typically yields a net of 36 to 38 ATP molecules through glycolysis, the Krebs cycle, and oxidative phosphorylation. This number can vary slightly depending on the specific cell type and the efficiency of the electron transport chain. Here's a breakdown: Glycolysis: Produces 2 ATP molecules directly. Krebs Cycle: Produces 2 ATP molecules directly. Electron Transport Chain and Oxidative Phosphorylation: This is where the majority of ATP is produced, yielding approximately 32-34 ATP molecules.
