WebDec 30, 2024 · Figure 5.7. 13. Glycogen is a storage form of glucose that is broken down by glycogen phosphorylase (linear a (1-4) bonds) and debranching enzyme (branchpoint α (1-6) bonds). Phosphorylase is a homodimer that is allosterically controlled by glucose, G6P, and ATP negatively, and by AMP positively. In addition to allosteric binding sites for ... WebA. CHO Aerobic Metabolism Glycolysis, Krebs Cycle and ETC o Anaerobic metabolism - pyruvate enters krebs cycle o Lower intensities of exercise o Pyruvate does NOT accumulate o Cleve H’s to enter ETC to make ATP o More reactions = longer to produce energy The rate of energy production is dictated by the number of reactions, more reactions= slower … sic code industrial machinery

WebGlycolysis This process does not require oxygen (it is anaerobic ). The production of pyruvate from glucose involves the production of several intermediate molecules . WebJul 4, 2024 · The next several steps are exactly the same as glycolysis only the process is in reverse. The second step that differs from glycolysis is the conversion of fructose-1,6-bP to fructose-6-P with the use of the enzyme fructose-1,6-phosphatase. The conversion of fructose-6-P to glucose-6-P uses the same enzyme as glycolysis, phosphoglucoisomerase. Webglucose will be converted to glycogen. Later, when blood sugar begins to fall, glycogen can be broken down into monomers of glucose again, which will enter glycolysis. Glycogen synthesis is an important process to help us store" sugar for use when we are not eating but need to maintain appropriate blood sugar levels. sic code major groups
