"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. " - Can a cell bypass and skip glycolysis

WebMar 5, 2024 · The process itself does not use oxygen; however, glycolysis can be coupled with additional metabolic processes that are either aerobic or anaerobic. Glycolysis takes place in the cytoplasm of prokaryotic and eukaryotic cells. It begins with a single six-carbon glucose molecule and ends with two molecules of a three-carbon sugar called pyruvate. WebThe glycolytic pathway can be used for the synthesis of glucose from simpler molecules through gluconeogenesis. Gluconeogenesis is the synthesis of glucose from nonsugar sources, especially amino acids and TCA cycle intermediates.
