The major end products of the electron transport chain are: a. glucose and amino acids b. dietary fiber and ammonia c. water, carbon dioxide and ATP d. carbon, nitrogen and hydrogen

C) water, carbon dioxide and ATP

Explanation:

The electron transport chain is the sequential step chain reaction that takes place in the mitochondrial membrane.

In the electron transport chain, the electron moves down various protein complexes that utilize the reduced freer energy of the electron to transport the proton out of the mitochondria.

This causes proton gradient across the membrane and when the protons flow into the mitochondrion back through the ATP synthase then ATP is produced. On the pathway of the electron transport chain, the carbon dioxide and the metabolic water are also produced.

Thus, Option-C is correct.
