Document Summary

Bc1502 introduction to cell and molecular biology. Going to use charged up nadh/fadh2 molecules. Process is comprised of two systems: electron transport chain (system): Chemiosmosis atp synthase (works like a turbine) A series of electron carriers with increasing affinity for electrons, transfers electrons from electron shuttles (nadh, fadh2) to oxygen: complex 1 nadh drops its electrons, complex 2 fadh2 drops its electrons. As this is happening, h+ ions will be pumped across the membrane, using the energy of electron transport. H+ gradient is made that provides the energy for. Atp synthase to convert adp to atp: taking h+ ions to reduce oxygen to make water, mechanical force, electron transfer system (ets or etc) Protein complex: i, ii, iii, iv contain electron carriers. Complex i accepts electrons from nadh, h+ pump. Complex ii -> accepts electrons from fadh2. Complex i, iii and iv are pumps: oxidative phosphorylation (chemiosmosis) Produces h+ gradient potential energy in the form of an ordered system c. i.
