Electron transport and oxidative phosphorylation are performed by protein complexes in the mitochondrial
A) outer membrane.
B) intermembrane space.
C) inner membrane.
D) matrix.

Question

Quizplus · Accepted Answer

Electron transport and oxidative phosphorylation occur in the inner membrane of the mitochondria, where the protein complexes involved in oxidative phosphorylation are located. The outer membrane is mainly involved in the transport of molecules into and out of the mitochondria, while the intermembrane space is the space between the outer and inner membranes. The matrix contains enzymes involved in the tricarboxylic acid cycle and fatty acid oxidation, but not the protein complexes involved in electron transport and oxidative phosphorylation.
