WebMolecules that increase the activity of an enzyme are called activators, while molecules that decrease the activity of an enzyme are called inhibitors. There are many kinds of molecules that block or promote enzyme function, and that affect enzyme function by different routes. WebExplain how temperature, pH, cofactors, and enzyme inhibitors can affect enzyme activity. Temperature affects enzyme activity because enzymes are made of proteins and as the temperature raises, the protein's molecular structure will be more and more unstable until it denatures and breaks apart. easy check stk https://x-tremefinsolutions.com
