Classs 26: Mitochondrial Electron Transport Chain and Chemiosmosis

Mitochondrial matrix

the space within the inner membrane

mitochondrial inner membrane

electron transport chain site

mitochondrial outer membrane

separates inner membrane space from cytoplasm

mitochondrial intermembrane space

space between inner membrane and outer membrane

NADH

electron carrier

FADH2

electron carrier

electron transport chain

a series of four protein complexes that use redox reactions to make an electrochemical gradient and create ATP by oxidative phosphorylationharvests electrons from NADH and FADH2

electron transort complex I-III

harvests electrons from NADH and FADH2 and then are transported to complex IV

Electron transport complex IV

Uses electrons and oxygen to make water

ATP synthase

uses proton gradient to drive synthesis of ATP
