Question
TCA cycle enzymes are located in
cristae
outer membrane
mitochondrial matrix
mitochondrial intermembrane space
Solution
C.
mitochondrial matrix
TCA cycle enzymes are soluble proteins located in the mitochondrial matrix space, except for succinate dehydrogenase, which is an integral membrane protein that is firmly attached to the inner surface of the mitochondrial inner membrane, where it communicates directly with components in the respiratory chain.
