Answer 21

Oxidative Phosphorylation

Question 22

Importance of Oxidative Phosphorylation

Answer 22

ATP synthesis by ATP synthase powered by the proton gradient.

Question 23

Input if oxidative phosphorylation

Answer 23

Proton gradient, ADP, Pi

Question 24

Output of oxidative phosphorylation

Answer 24

ATP

Question 25

Where does oxidative phosphorylation occur ?

Answer 25

Occurs in the inner mitochondrial membrane.

Question 26

As the electrons move through the complexes the create

Answer 26

Flow of protons h plus ions across the membrane creating a protein gradient

Question 27

Oxidative phosphorylation is

Answer 27

Apart of electron transport chain

Question 28

Oxidative phosphorylation is the part of the electron transport chain where the energy stored

Answer 28

in the proton gradient is harnessed to synthesize adenosine triphosphate (ATP), which is the primary energy currency of cells.
