Question

What is the difference between substrate-level phosphorylation and oxidative phosphorylation?

Answer 1

Substrate-level phosphorylation:

Substrate-level phosphorylation is a metabolic process that produces ATP or GTP by directly transferring a phosphate group from a substrate to ADP or GDP.

Oxidative phosphorylation:

The mechanism through which ATP generation is linked to the flow of electrons along the mitochondrial electron transport chain and the accompanying consumption of oxygen is known as oxidative phosphorylation.
