WebBiology questions and answers. 11-Phosphofructokinase, the major flux-controlling enzyme of glycolysis is allosterically inhibited and activated respectively by A) ATP and PEP B) AMP and Pi C) ATP and ADP D) Citrate and ATP 12- Which of the following regulates glycolysis steps? A) Phosphofructokinase B) Hexokinase C) Pyruvate kinase … WebThe molecules that bind to the regulatory sites on enzymes may inhibit the enzyme's activity or enhance the enzyme's activity. Glycolysis breaks down glucose and forms ATP, so when the cell has enough ATP, the cell should tell glycolysis to stop. Therefore, it seems reasonable that ATP would be a negative regulator of enzymes partaking in ... WebAug 15, 2024 · Control of these enzymes, such as hexokinase, phosphofructokinase, glyceraldehyde-3-phosphate dehydrogenase, and pyruvate kinase, can regulate glycolysis. ... at least initially. The mechanisms responsible for this effect include allosteric regulators of glycolysis (enzymes such as hexokinase). The “Pasteur effect” appears to mostly occur ... soft loc install
