Question

Citric acid cycle takes place in

• A. Mitochondria
• B. Liver
• C. Nucleic acid

Hint:

Mitochondria = Powerhouse = Krebs Cycle site.

Answer 1

The Correct Option is A

Step 1: Concept
The Citric Acid Cycle (Krebs cycle) is a key aerobic metabolic pathway for energy production.

Step 2: Meaning
It occurs within specific compartments of the eukaryotic cell where the necessary enzymes and electron carriers are located.

Step 3: Analysis
Glycolysis occurs in the cytosol, but the products move into the mitochondrial matrix, where the Citric acid cycle processes them into ATP, $CO_{2}$, and water.

Step 4: Conclusion
The mitochondrial matrix is the definitive site for the Citric acid cycle.

Final Answer: (A)
