ENERGY-INVESTMENT STAGE Requires 2 ATPS to get gylcolosis started *Step 1. Glucose is phosphorylated by ATP to form Glucose 6-phosphate *Steps 2 and 3. The atoms of glucose 6-phosphate are rearranged to form fructose 6-phosphate. Fructose 6-phosphate is phosphorylated by ATP to form fructose 1, 6-bisphosphate LYSIS STAGE Step 4. Fructose 1,6-biphosphate is cleaved to form glyceraldehyde 3-phosphate (G3P) and dihydroxyacetone phosphate (DHAP). Step 5. DHAP is rearranged to form another G3P. So far, glucose has been split into 2 molecules of G3P ENERGY-CONSERVING STAGE *Step 6. Inorganic phosphates are added to the 2 G3P & 2 NAD+ are reduced. Oxidation of glyceraldehyde-3-phosphate: Oxidation- removal of electrons Reduction- addition of electrons

Unformatted text preview: • (oil rig) • 2 G-3-P are oxidized, 2NAD+ are reduced, 2 1, 3- bisphophoglycerate are produced. • First oxidation-reduction reaction in glycolysis ^ • **Glyeraldehyde is oxidiced, NAD is reduced to NADH (question on test)** **Step 7. Two ADP are phosphorylated by substrate-level phosphorylation to form 2 ATP. **substrate-level phosphorylation-a high energy phosphate group is transferred to AP to form ATP, fist place ATP made into gylcolysis Step 10. Two ADP are phophorylated by substrate-level phosphorylation to form 2 ATP and 2 pyruvic acid These are for the box below, the second one finishes the last bullet:-Total of 4 ATP’s formed in this part of the pathway -net gain of 2 ATP’s in glycolysis...
