Description
Biochemistry 2EE3 Lecture 21 • • • • • • • Host cells provide food for mitochondria • Mitochondria has two membranes • Inner membrane folds many times to increase the surface area, this is important because it is the surface of the mitochondria where all the proteins in the ETC are localized • We also produce a lot of water molecules along with CO2 which is why the inner membrane is permeable to water molecules • • • Outer membrane - split in two parts • White spots are proteins on the membrane • Small number of transmembrane proteins in the outer membrane • Alot of transmembrane proteins in the inner membrane • Inner membrane is heavily packed with molecules • • Need to transfer NADH from glycolysis to mitochondria • However we don't really need NADH itself, we need its high energy electrons • Reaction 1 is catalyzed by 3-phosphoglyc
