What must enzymes maintain to function properly?

Enzymes are highly specialized proteins that catalyze biochemical reactions in living organisms. To function properly, they must maintain their three-dimensional shape, which is critical for their activity. This specific shape allows enzymes to bind to their substrate molecules effectively, forming an enzyme-substrate complex that facilitates the chemical reaction.

The three-dimensional structure of an enzyme is determined by its amino acid sequence and can be affected by various factors, including temperature and pH levels. If the enzyme's shape is altered, often referred to as denaturation, it can lose its functionality, meaning it would not effectively catalyze reactions. Therefore, maintaining the precise three-dimensional structure is essential for enzyme activity and, consequently, for metabolic processes within the cell.
