MP4. Regulation of Metabolic Pathways: How Is It Regulated?
WebMar 20, 2024 · We will also see that the regulation of the pathway can vary depending on cell type and cellular needs. Hexokinase Regulation One of the primary mechanisms that controls the regulation of the hexokinase step in glycolysis is the presence of different hexokinase enzymes in different cellular types. WebThus, if a cell wants to control the activity of a metabolic pathway, it needs to regulate the activity of one or more of the enzymes in that pathway. The primary target for regulation of a biochemical pathway is often the enzyme that catalyzes the pathway’s first committed step (that is, the first step that is not readily reversible). subway downloadable menu pdf
