The sixth step in glycolysis ( Figure 7.7) oxidizes the sugar (glyceraldehyde-3-phosphate), extracting high-energy electrons, which are picked up by the electron carrier NAD +, producing NADH. The sugar is then phosphorylated by the addition of a second phosphate group, producing 1,3-bisphosphoglycerate. great in gaelic

WebThis occurs because RBCs have the enzyme-mediated metabolic machinery necessary to produce energy (ATP) and specialized metabolic pathways to protect against external oxidant stresses. In the absence of normal enzyme function, RBC survival is shortened, a manifestation of the hereditary nonspherocytic hemolytic anemias (HNSHAs). WebThe oxidative phase: The “oxidative” word of this phase comes from the process of oxidation. Oxidation is the breakdown of a molecule as it loses at least one of its electrons.This phase is made up of 2 irreversible steps: Step 1: Glucose-6-phosphate is oxidized to form lactone. NADPH is produced as a byproduct of this reaction as NADP ... Web##### RBC Metabolic Pathways and Hemoglobin.
