WebStep 6. 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. WebJan 19, 2024 · The red blood cell (RBC) is unique in terms of its structure and function when compared to other cells in the blood and body. Its anucleated characteristic and biconcave shape (indicative of high surface area to volume ratio) render it deformable. This deformability is useful during circulation when the red blood cell has to traverse …
