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

Answer 1

Both are means of producing and storing energy in form of ATP

In oxidative phosphorylation, a substrate is oxidized in the presence of specific enzymes, releasing energy, whereas in substrate level phosphorylation, a substrate breaks down and releases energy on its own.

Both situations involve the release of energy, which is primarily stored as ATP and happens during the Krebs cycle and glycolysis.

While oxidative phosphorylation uses a proton gradient across the inner mitochondrial membrane to drive ATP synthesis, substrate-level phosphorylation directly transfers a phosphate group to ADP.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
