Question

Proton flow through the ATP synthase enzyme

Answer 1

Answer:

The answer is A. provides the energy for adding a phosphate to ADP to make ATP.

Explanation:

The ATP synthase is an enzyme located in the inner membrane of the mitochondria. It creates a hydrophilic channel across the inner mitochondrial membrane that allows a flux of protons that moves down an electrochemical gradient. These H+ ions are then used as an energy source during the enzymatic reaction that converts ADP + Pi to ATP. This process is called chemiosmois and it’s not unique to cellular respiration, it is also used in photosynthesis and other processes involved in homeostasis. The proton-motive force, as some people refer to the proton gradient was first proposed by Peter Mitchel in the 1960’s as the chemiosmotic theory.
