Unformatted text preview: Phosphoryla2on of ADP The process of SLP always involves 2 reac2ons, each catalyzed by an enzyme. Animal Metabolism (II)! Glycolysis Reactions #6 & 7! Reac2on # 6: G 3- P + NAD+ + Pi → 1,3- bisphosphoglycerate + NADH + H+ Oxida2on/Reduc2on Reac2on Reac2on # 7: 1,3- bisphosphoglycerate ADP → 3- phosphoglycerate + ATP Phosphoryla2on Enzyme Type: Purpose: Rx. 5 Animal Metabolism (II)! (II)! Animal Metabolism Rx. 6 Glucose Catabolism & Glycolysis! Glucose Catabolism & Glycolysis! Reac2on 6: Oxida2on- Reduc2on Rxn. Rx. 7 Rx. 8 Rx. 9 1. NAD+ Rx. 10 Reduced to NADH 2. Aldehyde Oxidized to Carboxylic Acid How do you know it is a redox rxn.? Animal Metabolism (II)! A small detour from Glycolysis! How can we tell when a C has been oxidized? A qualita2ve analysis of oxida2on – reduc2on rxn….. When a C loses bonds with H and gains bonds with either C, O, or S It undergoes oxida2on This based on the concept of electronega2vity…… Low High H < C < S < O Animal Metabolism (II)! A small detour from Glycolysis! How can we tell when a C has been oxidized? Atoms with higher electronega2vity pull e- from atoms with lower electronega2vity Example: CH4 → CO2 H H – C – H H O = C = O C reduced in CH4 C oxidized in CO2 (C pulling e- from H) (O pulling e- from C) Rx. 5 Animal Metabolism (II)! (II)! Animal Metabolism Rx. 6 Glucose Catabolism & Glycolysis! Glucose Catabolism & Glycolysis! Reac2on 6: Oxida2on- Reduc2on Rxn. Rx. 7 G- 3- P 1,3- BPG Rx. 8 Alde...
