Question

What are the differences between oxidative, substrate an photophosphorylation?

Answer 1

Chemical bonds are energy source for oxidative phosphorylation, while sun energy is used for photo phosphorylation.

Explanation:

The phosphorylation is a process of formation of ATP from ADP.
In this process of photosynthesis, the energy for phosphorylation is supplied from sunlight. It is called as photo phosphorylation.
In the oxidative phosphorylation, energy for phosphorylation is provided from the oxidation of the substrate. So, it is called as oxidative phosphorylation. Thanks.
