Which process occurs in the mitochondrial matrix?
Correct Answer
Option B is the correct answer.
Detailed Explanation
The mitochondrial matrix is the fluid-filled space inside the inner membrane. It contains the enzymes for the Krebs cycle (also called the Citric Acid Cycle or TCA cycle) and beta-oxidation of fatty acids.
