Micro Notes 9-28-10 Metabolism - the totality of all the chemical reactions that occur in an organisms cell. Catabolism - the breakdown of molecules in a cell and that usually coupled with the production of energy. If you have a molecule and you are breaking it down, you are breaking bonds, and you are breaking energy Anabolism - the biosynthesis of molecules and that’s usually coupled with the use of energy. Energy is consumed. When breaking bonds, you are releasing energy. Amphibolic - these pathways can go forwards or backwards. Used for both catabolism and anabolism. Can build molecules up and break them down. 1.) Embden-Meyerhoff Pathway (mother pathway—1) Start of with glucose and you add a phosphate group to it. Normally you get that group from ATP. When you strip it of phosphate group you get ADP. That makes glucose-6-phosphate. Glucose is a 6-carbon sugar and if you rearrange then you can turn it into fructose-6-phosphate. Then you add another phosphate to that fructose-6-phosphat from ATP that turn into ADP to get fructose1-6-biphosphate. Then it is broken into 2 molecules: 1) dihydroxy acetonephosphate 2) glyceraldahide-3-phosphate (G3P) The (1) is then converted to G3P(net production is 2 ATPs
