Factors that may affect the active site and enzyme function include: Temperature. A higher temperature generally makes for higher rates of reaction, enzyme-catalyzed or otherwise.

WebMay 29, 2013 · The ribosomes of the cell make proteins and since enzymes are proteins, ribosomes make these also. WebIn order to mark enzymes that should be sent to lysosomes to help degrade unwanted molecules, the Golgi has to bind them with a mannose 6-phosphate tag, like a shipping label. However, in patients with I-cell disease, one of the proteins that make this tag is mutated, and cannot do its job, like a broken label machine.

WebGene regulation is the process of controlling which genes in a cell's DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA.
