During glucose activation phase of glycolysis

WebThe first step in glycolysis is a priming reaction, where a phosphate group is added to glucose using ATP. This reaction is important for its ability to trap glucose within the cell. Whereas glucose can easily traverse the plasma membrane, the negatively charged phosphate group prevents G6P from crossing, so cells can stock up on WebThe second half of glycolysis is known as the pay-off phase, ... During fasting (no glucose available), glucagon activates protein kinase A which phosphorylates pyruvate kinase to inhibit it. An increase in blood sugar leads to secretion of ... The overall process of glycolysis is: Glucose + 2 NAD + + 2 ADP + 2 P i → 2 pyruvate + 2 NADH + 2 H ...
