3/31/11 ATP-citrate lyase In the cytoplasm citrate that has been exported from the mitochondria can be converted to Acetyl-CoA by the enzyme atp-citrate lyase Atp+citrate +Coa +yields adp +pi +oxoloaceteate+acetyl coa Malic Enzyme-uses NADP+ to yield NADPH The glyocylate cycle Plants and some bacteria can do this. Animals cannot Use to acetyl coa to make oxaloacetate and gluconeogensis- for growing and intermediate for making the woody parts of plants Electron Transport and oxidative phosphorylation ADP + Pi yields ATP H=H^+ + e^- Come out of the citric acid with reduced NADH About 3.6 million years go to almost 2 years ago the world was anaerobic Redox Potentials Many reactions of catabolic pathways involve oxidations of substrates

Unformatted text preview: Redox potential- the more positive the stand reduction potential the greater the frequency for the redox couples oxidized form to accept elections and become reduced.-Spontaneous delta E= spontaneous reaction (just the opposite as delta G) Nernst Equation • E=electron potential • F=faraday constant • The ratios are not enormous, that means we can get a fair idea of what’s going on without knowing the other variables. Look at table 15-1 Oxidative phosphorylation In mitochondria In cytoplasm Take electrons on NADH and combine it with oxygen to make water Complex 1 Function NADH is a 2 electron carrier...
