What powers the ATP synthase enzyme at the end of aerobic respiration?
a. energy from ATP
b. energy from NADPH
c. energy from the splitting of water
d. energy from the flow of hydrogen ions


Sagot :

Answer: D. energy from the flow of hydrogen ions

Explanation:

During aerobic respiration, a proton gradient is established across the inner mitochondrial membrane by the electron transport chain. The flow of hydrogen ions (protons) back into the mitochondrial matrix through ATP synthase drives the synthesis of ATP from ADP and inorganic phosphate. This process is known as chemiosmosis.
