WebControls enzyme levels; Control of catalytic activity The number of enzymes in a cell depends on the rate of synthesis and degradation of a product. The catalytic activity of an enzyme can be changed positively (increased activity) or negatively (decreased activity) through conformational changes or structural modifications with covalent bonds. WebJan 27, 2015 · Nucleotide synthesis is an energy intensive process that uses multiple metabolic pathways across different cell compartments and several sources of carbon and nitrogen. The processes are regulated at the transcription level by a set of master transcription factors but also at the enzyme level by allosteric regulation and feedback …
