Studies of the inner mitochondrial membrane reveal its composition to be approximately 20% lipid bilayer and 80% protein.What is true of these proteins?
A) Abundant collagen proteins form connective tissues to strengthen the membrane against the pH gradient.
B) High levels of proteins are required to metabolize glucose in the glycolysis pathway for rapid energy production.
C) The proteins form highly folded cristae structures.
D) The proteins are largely electron transport complexes and ATP synthase enzymes.

Question

Quizplus · Accepted Answer

The inner mitochondrial membrane contains proteins that are largely electron transport complexes and ATP synthase enzymes, which are essential for the production of ATP via oxidative phosphorylation. Collagen proteins are not found in the inner mitochondrial membrane and glycolysis, while a crucial energy pathway, occurs outside of the mitochondria in the cytoplasm. Additionally, the highly folded cristae structures are formed by the lipid bilayer, not the proteins.
