NettetBecause enzymes guide and regulate the metabolism of a cell, they tend to be carefully controlled. In this article, we’ll take a look at factors that can affect or control enzyme activity. These include pH and temperature (discussed in the active site article), as well as: Regulatory molecules. NettetEvidence indicates that phosphofructokinase may be the rate-limiting factor of the EMP pathway and that it may be inactivated by oxidation has led to proposals that the enzyme is the mediator of the Pasteur effect because: (1) phosphofructokinase, like the overall EMP pathway, is inactivated by oxidation and reactivated by reduction. (2)
