Question

As the protons move down their concentration gradient in the electron transport chain, what's happening with the electrons in the chain? A. They combine with oxygen to form water B. They convert ADP to ATP C. They split apart from oxygen D. They take a phosphate group off ATP

Answer 1

Answer:

A. They combine with oxygen to form water

Explanation:

Answer 2

Answer:

Option B, They convert ADP to ATP

Explanation:

The H+ ions uses energy (released by the passage of electrons from higher energy level to lower energy level) for moving into intermembrane space thereby establishing a proton gradient.The proton moves through this concentration gradient by using hydrophilic tunnels. In the mitoc hondrial membrane, H+ ion move down their electrochemical gradient with the assistance of ATP synthase (an enzyme). ATP synthase causes the conversion of ADP to ATP thorugh chemiosmosis where energy from a proton gradient is used to make ATP.

Thus as the protons move down their concentration gradient in the electron transport chain, they convert ADP to ATP
