WebMar 13, 2024 · DHAP, an intermediate of glycolysis, can be converted to glycerol phosphate in the liver and adipose tissue. This can feed into biosynthetic pathways, such as triglyceride and phospholipid biosynthesis, which also recycles NADH. 1,3-BPG can also be converted to 2,3-BPG in red blood cells to alter the affinity of haemoglobin for O 2. shard traducirWebStep 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. shard tower heightWebJun 27, 2012 · Glycolysis vs Gluconeogenesis Cells take energy by the hydrolysis of ATP molecules.
