Question

The folded inner membrane of the mitochondria are called: a. matrix b. cisternae c. cristae d. matrae
Options
A matrix
B cisternae
C cristae
Correct Answer
D matrae
Correct Answer

Option C is the correct answer.

Detailed Explanation

The inner membrane of the mitochondrion is highly folded into structures called cristae. These folds greatly increase the surface area available for the electron transport chains and ATP synthase complexes, which are crucial for ATP production. The matrix is the fluid-filled space inside the inner membrane.

Hint

These folds are like the 'crests' inside the mitochondria, maximizing surface area.
