What role does the electron transport chain play in cellular respiration?
It generates a proton gradient across a membrane.
It directly produces ATP from glucose.
It transports oxygen to the mitochondria.
It breaks down fatty acids into acetyl-CoA.
How is ATP synthesized in the mitochondria during chemiosmosis?
By the enzyme ATP synthase utilizing the energy from the proton gradient.
Through the breakdown of glucose directly in the matrix.
By converting ADP to ATP in the cytoplasm.
By the process of glycolysis occurring in the inner mitochondrial membrane.
What is the final electron acceptor in the electron transport chain?
Carbon dioxide
NAD+
Oxygen
FAD
