Calculating ATP

Oxidation of one molecule of acetyl coA is the one Krebs cycle. In one Krebs cycle, produce 3 NADH, 1FADH2, 1 GTP 1 NADH = 3 ATP x 3 1FADH2 = 2 ATP x 1 1GTP = 1ATP ______________ Total: 12 ATP U have three acetyl CoA = 3 x ...

Fatty acid Oxidation-ATP yeild

... to acetyl-CoA and synthesized from acetyl-CoA. Although the staring material of one process is identical to the product of the other, fatty acid oxidation is not the simple reverse of fatty acid biosynthesis. It is an entirely different process taking place in separate compartment of the cell. ...

ETC - purpose of having different dehydrogenases?

... great latitude in adjusting (delta)P generated during respiration. Since a large (delta)P can drive reversed electron transport and thus slow down oxidation of NADH and quinol, it may be an advantage to be able to direct electrons along alternate routes that bypass coupling sites and translocate ...
