Definitions:

Phosphofructokinase

An enzyme that plays a critical role in regulating the rate of glycolysis, controlling the conversion of fructose 6-phosphate to fructose 1,6-bisphosphate.

ATP Levels

The concentration of adenosine triphosphate, a molecule that carries energy within cells, facilitating metabolic processes.

Electron Transport Chain

A series of complexes that transfer electrons from electron donors to electron acceptors via redox (reduction and oxidation) reactions, and the transfer of electrons is coupled with the transfer of protons (H+ ions) across a membrane, which generates ATP.

Proton Pumping

The active transport of hydrogen ions (protons) across a membrane, often creating a gradient used for energy production in cells.
