  1. Question 1

    Q1. The inner mitochondrial membrane is highly convoluted, forming structures known as cristae. What is the primary functional advantage of these folds?

    • A) Increasing matrix volume
    • B) Increasing surface area for ETC
    • C) Storage of glycogen
    • D) Facilitating glycolysis

    Answer: Increasing surface area for ETC

    Explanation: Cristae provide extensive surface area for embedding ETC components and ATP synthase. The matrix is wrong because it houses soluble Krebs enzymes.
