WebDuring the cana treatments (both 10 and 100 µM), the mitochondrial oxidative phosphorylation in the HUVECs was impaired, and the reduced glycolysis rate, together with the impaired mitochondrial oxidative phosphorylation, produced a metabolically quiescent state in the cells to conserve the cellular functions. WebSubstrate-level phosphorylation means that a phosphate is transferred to ADP from a high-energy phosphorylated organic compound. We will see in the section on metabolic pathways that a couple of the enzymes in glycolysis make ATP through substrate-level phosphorylation, as well as an enzyme in the citric acid cycle. However, only a small …

WebThe first step in glycolysis is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose. WebDec 30, 2024 · The enzyme is so named because it is a kinase (puts a phosphate group on) that acts on a hexose (six-carbon sugar). In this case, it places the phosphate on the 6-carbon of glucose. However, hexokinase can also phosphorylate other hexoses such as fructose and mannose (all in the D-conformation).
