Zoom in on Glycolysis: Reaction 6 Oxidoreductase Enzyme -formation of 1,3-bisphosphoglycerate is catalyzed by an oxidoreductase enzyme moves electrons (and hydrogen) from one molecule to another glyceraldehyde-3-P 6 1,3-BPG 3-PG 2-PG PEP pyruvate NAD NADH H ADP ATP H₂O ADP ATP Look at the drawing of this reaction on the right. See how the bond between upper carbon and hydrogen in the top molecule has been replaced with a bond between carbon and the more electronegative atom, phosphorous in the bottom molecule? This is how carbon becomes more oxidized. In this process, the hydrogen and electrons associated with it were moved from the top carbon to NAD+ glyceraldehyde- dehydrogenase 3-P Recognizing oxidoreductases: NAD+, FAD, and NADP+ are C-H C P glyceraldehyde-3-phosphate electron carriers, so if they are involved in the reaction you know it is an oxidation-reduction. C OH C P Pi C OH NAD+ NADH + H+ C P 1,3-bisphosphoglycerate
First post. 1. Choose reaction #6 or # 10 in glycolysis and write out the complete reaction. Then, answer the following questions about this reaction. Explain your reasoning for each answer. a. Is it coupled? b. Is it catalyzed by a transferase or an oxidoreductase or neither? c. Is Q> or < or to K? 2. Reflect on Week 7 concepts and then describe one concept you are still struggling to understand. Then, ask a question that a group member can answer.
