1. Temperature: Enzymes have an optimal temperature range at which they function best.
* Increasing temperature: Generally, enzyme activity increases with temperature up to a certain point. This is because increased kinetic energy leads to more frequent collisions between enzymes and substrates.
* Exceeding the optimal temperature: At very high temperatures, enzymes can denature, meaning their structure changes and they lose their ability to function.
2. pH: Enzymes also have an optimal pH range.
* Changes in pH: Changes in pH can disrupt the ionic bonds and hydrogen bonds that hold an enzyme's structure together. This can alter the shape of the active site and reduce enzyme activity.
Other factors that can affect enzyme activity include:
* Substrate concentration: Increasing substrate concentration generally increases enzyme activity until all active sites are saturated.
* Presence of cofactors: Some enzymes require cofactors (e.g., metal ions, vitamins) to function.
* Presence of inhibitors: Inhibitors can bind to enzymes and block their activity.
