WebAug 7, 2024 · Glycogen is found in most cell types, where it serves as a reservoir of glucosyl units for adenosine triphosphate (ATP) generation from glycolysis. Glycogen is degraded mainly to glucose 1-phosphate, which is converted to glucose 6-phosphate. In skeletal muscle and other cell types, glucose 6-phosphate enters the glycolytic pathway … The first five steps of Glycolysis are regarded as the preparatory (or investment) phase, since they consume energy to convert the glucose into two three-carbon sugar phosphates (G3P). The first step is phosphorylation of glucose by a family of enzymes called hexokinases to form glucose 6-phosphate (G6P). This reaction consumes ATP, but it acts to keep the glucose concentration low, promoting continuous transport of glucose into the cell through the plasma m…
