Quizplus · Accepted Answer

The key characteristic of enzyme behavior is that the active site of an enzyme orients its substrate molecules, thereby promoting interaction of their reactive parts. This allows enzymes to facilitate and accelerate specific chemical reactions in the cell. Enzyme shape may change during catalysis, enzymes may have multiple active sites, and enzyme activity is generally affected by pH and temperature. Not all enzymes require coenzymes for catalysis.
