What are the consequences of a proton gradient and how could a gradient be used in the mitochondria?

At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain. The energy that is being released pumps hydrogen out of the matrix space. The gradient is created by this process, drives hydrogen back through the membrane, through the ATP synthase. Thus, the ATP is very essential for life, and that a proton gradient and membrane prospective are vital in order for ATP synthesis to occur in the mitochondria. However, mitochondria is very active that it can converse its process. Complex V is the enzyme liable for final ATP synthesis at the end of oxidative phosphorylation.

Idon't know how to do this but maybe ask your mom or dad
