Definitions:

Substrate-Level Phosphorylation

Substrate-level phosphorylation is a metabolic process where a phosphate group is directly transferred from a substrate molecule to ADP, forming ATP, occurring in glycolysis and the citric acid cycle.

Phosphorylated Intermediate

A molecule that has been temporarily phosphorylated (had a phosphate group added) during a metabolic reaction, often playing a crucial role in energy transfer.

Electron Transport

A series of chemical reactions that transfer electrons from electron donors to electron acceptors via redox reactions and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.

Proton Gradient

A gradient of hydrogen ions across a membrane, often used in the process of generating ATP in cells, particularly within the mitochondria during cellular respiration.
