Question

How does substrate level phosphorylation and oxidative phosphorylation differ from one another?

Answer 1

Hint: The Substrate level phosphorylation and Oxidative phosphorylation are 2 major types of phosphorylation processes that occur inside the body of a living organism. Phosphorylation is the word used to understand the formation of ATP which describes the transfer of phosphate groups from one compound to another.

Complete answer:
 The organisms store energy in the form of ATP (adenosine triphosphate). In the eukaryotes mitochondria is the cell organelle which produces ATP (adenosine triphosphate) but some of the ATP are also produced in Cytoplasm.
The main aspect which differentiates Substrate level phosphorylation and Oxidative phosphorylation is that Substrate level phosphorylation is a direct phosphorylation of ADP with a phosphate group by using the energy obtained from coupled reaction where oxidative phosphorylation is the production of ATP from the oxidized NADH and FADH2.
The substrate level phosphorylation mainly occurs in the cytoplasm and mitochondria matrix. Where, Oxidative phosphorylation occurs on the inner membrane of mitochondria.
A phosphate group is directly removed from a substrate by a coupled reaction and transferred into ADP in Substrate level phosphorylation whereas in Oxidative phosphorylation Phosphate groups are added from the energy released in the electron transport chain.
When talked about redox potential the substrate is less in substrate level phosphorylation where as in Oxidative phosphorylation the redox potential is more

Note: The substrate level and oxidative phosphorylation add a phosphate group to ADP, there are Enzymes involved in both substrate level and oxidative phosphorylation. Both of the substrate level and oxidative phosphorylation processes can occur in the mitochondria.
