A mutant protist is found in which some mitochondria lack an inner mitochondrial membrane. Which of the following pathways would be completely disrupted in these mitochondria?

Question

Quizplus · Accepted Answer

The inner mitochondrial membrane is where the electron transport chain and ATP synthase complexes are located, which are essential for oxidative phosphorylation to occur. Without the inner mitochondrial membrane, oxidative phosphorylation would not be possible in these mitochondria. Glycolysis and alcoholic fermentation both occur in the cytoplasm and do not require the inner mitochondrial membrane.
