WebCofactors can be subdivided into either one or more inorganic ions, a complex organic or metalloorganic molecule called a coenzyme. The iron in heme acts as a prosthetic group. Heme is therefore sometimes referred to as a Metalloprotein. WebEnzyme activity is affected by various factors, including substrate concentration and the presence of inhibiting molecules. The rate of an enzymatic reaction increases with …

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. WebEnzyme activity is affected by various factors, including substrate concentration and the presence of inhibiting molecules. The rate of an enzymatic reaction increases with increased substrate concentration, reaching maximum velocity when all active sites of the enzyme molecules are engaged.
