WebApr 7, 2024 · Some enzymes need other associated molecules to work. These molecules are called enzyme cofactors and they can be, for example, organic ions like mineral salts, or organic molecules. Inactive enzymes which are not bound to their cofactors are called apoenzymes. Active enzymes bound to their cofactors are called holoenzymes. 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.
