Definitions:

Chemiosmosis

Process by which phosphorylation of ADP to form ATP is coupled to the transfer of electrons down an electron transport chain; the electron transport chain powers proton pumps that produce a proton gradient across the membrane; ATP is formed as protons diffuse through transmembrane channels in ATP synthase.

Electron Acceptor

An electron acceptor is a chemical entity that accepts electrons transferred to it from another compound. It is crucial in redox reactions and processes such as respiration.

NADH

Nicotinamide adenine dinucleotide (NADH) is a coenzyme found in all living cells that is involved in redox reactions, carrying electrons from one reaction to another.

Fructose-1,6-bisphosphate

An important sugar molecule involved in glycolysis, the metabolic pathway that converts glucose into pyruvate, releasing energy.
