Question

quiz 6: cellular respiration quiz
the electron transport chain occurs
in the cytosol
in the membrane of the thylakoid
in the matrix of the mitochondria
in the cristae of the mitochondria

Explanation:

The electron - transport chain is part of cellular respiration. It occurs in the inner mitochondrial membrane, which is folded into cristae. The cristae increase the surface area for the reactions of the electron - transport chain to occur. The cytosol is where glycolysis occurs, the thylakoid membrane is related to photosynthesis, and the mitochondrial matrix is where the Krebs cycle occurs.

Answer:

In the cristae of the mitochondria
