Mitochondria are bounded by a double membrane. The inner-filled space is called the matrix, which contains ________ that break down carbohydrate products, releasing ________ to be used for ATP production.
A) DNA/energy
B) ribosomes/carbon dioxide
C) RNA/energy
D) enzymes/energy

Question

Quizplus · Accepted Answer

The matrix of mitochondria contains enzymes that break down carbohydrate products, releasing energy to be used for ATP production. Ribosomes are not present in the matrix and neither DNA nor RNA are directly involved in the breakdown of carbohydrates. Carbon dioxide is a by-product of cellular respiration, but it is not released from the matrix. Therefore, the correct answer is D) enzymes/energy.

Mitochondria Are Bounded by a Double Membrane
