Can a cell bypass and skip glycolysis
WebStep 1. The first step in glycolysis (Figure 9.1.1) 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. WebMar 10, 2024 · Deficiency in glycolytic enzymes such as hexokinase can lead to diabetes. Defects in pyruvate kinase can also lead to heart disease. The glycolysis pathway is important for the survival of tumor cells. Cancer cells often rely on glycolysis for energy because the Warburg effect allows them to bypass oxidative phosphorylation.
