Question

Oxidative phosphorylation involves the flow of both electrons and H+. Explain the roles
of these movements in the synthesis of ATP.

Answer 1

The role of Hydrogen ion movement in the electron chain to produce ATP is that

The chain in oxidative phosphorylation is an energy converter, that utilize the flow of electrons from NADH and FADH2 to pump H+ from the mitochondrial matrix into the intermembrane space.

The hydrogen ion gradient that is pumped as a result of this by the electron transport chain is used by ATP synthase to form ATP.

What is oxidative phosphorylation?

Oxidative phosphorylation or electron transport-linked phosphorylation refer to a form of metabolic pathway by which cells use enzymes to supply oxygen to good nutrients in order to release chemical energy so as to produce adenosine triphosphate. In eukaryotes, this takes place inside mitochondria.

Therefore, The hydrogen ion gradient that is pumped as a result of this by the electron transport chain is used by ATP synthase to form ATP.
