Question

Contrast the electron transport chain in photosynthesis with cellular respiration by identifying the source of the high-energy electron. In photosynthesis, the electron that travels through the electron transport chain in the thylakoid membrane comes from ? In cellular respiration, a molecule of what supplies the electron that travels through the electron transport chain?.

Answer 2

In photosynthesis, electrons that travel through the electron transport chain in the thylakoid membrane come from "water."

In cellular respiration, molecules of "NADH" supply some of the electrons that travel through the electron transport chain.
