WebSep 19, 2024 · Enzyme Inhibition. Enzymes are required for most, if not all, processes required for life. Enzymes catalyse a reaction by reducing the activation energy needed for the reaction to occur. However, enzymes need to be tightly regulated to ensure that levels of the product do not rise to undesired levels. This is accomplished by enzyme inhibition. WebDuring gluconeo- genesis, pyruvate kinase must be inactivated so that a futile cycle does not result. Thus, both high alanine and ATP levels inactivate pyruvate kinase. If glycolysis is …
