Each enzyme exhibits optimal activity at a specific pH range, dictated by its unique molecular structure and the nature of the catalyzed reaction. Deviations from this optimal pH can disrupt the ionic interactions and hydrogen bonding within the enzyme, leading to conformational changes that impair its functionality.

The concentration of substrates and enzymes significantly impacts enzymatic reactions. At low substrate concentrations, the rate of reaction is limited by the availability of substrates. As substrate concentration increases, the rate of reaction also rises until it reaches a point of saturation, where all enzyme molecules are engaged in catalysis. Similarly, varying enzyme concentrations directly influence the rate of reaction, with higher enzyme concentrations generally accelerating the reaction rate until saturation is achieved.

Inhibitors and activators are molecules that modulate enzyme activity. Inhibitors can bind to enzymes and impede their function, either reversibly or irreversibly. Conversely, activators enhance enzyme activity, often by binding to specific regulatory sites and inducing conformational changes that augment catalytic efficiency.
