1. Temperature: Enzymes have an optimal temperature at which they function best.
* Low temperatures: Slow down enzyme activity, as molecules move slower.
* High temperatures: Can denature (change the shape of) the enzyme, making it inactive.
2. pH: Enzymes also have an optimal pH range.
* Extreme pH levels (too acidic or too basic): can denature the enzyme by altering the charges on amino acids, disrupting its shape and function.
3. Substrate concentration: The rate of an enzyme-catalyzed reaction increases as the concentration of the substrate increases, up to a point.
* High substrate concentration: All active sites on the enzyme are occupied, and the reaction rate plateaus.
