Krebs cycle takes place in:
Correct answer: B. Mitochondrial matrix
- A. Dictyosomes
- B. Mitochondrial matrix
- C. Lysosomes
- D. Vesicles of endoplasmic reticulum
Explanation
The Krebs cycle takes place in the mitochondrial matrix, which is the innermost compartment of the mitochondria. It is the site where various reactions of the Krebs cycle occur, leading to the complete oxidation of acetyl-CoA derived from glycolysis.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
