Document Summary

Cellular respiration the catabolic (breakdown) pathways in which the chemical bond energy in organic molecules is released and trapped to build atp. Chemiosmosis an energy-coupling process in which the diffusion of protons through the atp synthase protein complex drives atp synthesis. Atp synthase a complex of membrane proteins that functions in atp synthesis from. Adp and a phosphate, using energy from protons flowing through the synthase from high concentration to low concentration. Redox reaction a chemical reaction in which an electron is transferred from one chemical substrate to another; gain of electrons is reduction, and loss of electrons is oxidation. Electron transport chain a series of membrane molecules that are reduced and oxidized as electrons move sequentially towards more electronegative acceptors, losing potential energy at each step. Fad (flavin adenine dinucleotide) a coenzyme carrier that serves as an electron shuttle as it is reduced to fadh2 in the krebs cycle and oxidized back to fad in the electron transport chain.
