PPT-Coenzymes Many enzymes contain

small nonprotein molecules and metal ions Coenzyme a complex organic or metalloorganic molecule Prosthetic groups are distinguished by their tight stable incorporation into a proteins structure by covalent or . Understanding:. Enzymes have an active site to which specific substrates bind. Enzyme catalysis involves molecular motion and the collision of substrates with the active site. Temperature, pH and substrate concentration affect the rate of activity of enzymes. Reactions. Most reactions take place in a number of steps which need to be carefully controlled if the cell is to function properly. Enzymes are the most important controllers of cellular reactions. Catalysts.
