Temperature And Enzyme Activity:
Increasing temperature means the molecules gain more kinetic energy and move faster resulting in more chances of successful collisions of enzymes and substrates forming enzyme-substrate molecules.
Every enzymes has its own optimum pH and temperature, where it shows higher activity (pH:it is very specific; temperature:mostly not more than 30-37degree C). Above or below this situation the enzymes activity may differs exponentially due to the biochemical changes.
If the temperature or pH ranges outside the optimal enzyme range then the enzyme will function less efficiently, or denature and lose all function.
R group bonds are broken, the enzyme come unfolded and as the form changes the function is destroyed. Some enzymes can return to their original form if conditions return to optimal for that enzyme.
A high temperature may denature an enzyme. The substrate will not fit perfectly onto the enzyme (as in the lock and key mechanism), and thus the chemical reaction will be slowed down.
temperature and pH are very important factor in enzyme activity because temperature can be define as the hotness or coldness of a body and an enzyme activity takes place in a body. pH is the acidity or alkalinity of medium therefore pH and temperature affect enzyme activity.
Each enzyme has its own ideal function range based upon, among others, pH and Temperature. Variation from these ideal, or best, settings will decrease the effectiveness of the enzymes' functions.
when acidity is high and when temprature is at an extreme, enzymes tend to lose effectivness, and even stop working altogether.
Ph level, enzyme concentration, substrate concentration etc
The activity of an enzyme is affected by temperature, pH and the concentration of the substrate.
Enzymes work best in the pH and temperature that they are " designed " for. A pepsin enzyme works best in the low pH environment of the stomach, while amylase works best at mouth temperature and ~ 7 pH. Heat and out of range pH can denature enzymes and not only affect their activity but inactivate them.

A low temperature can slow down enzyme activity and high temperatures can denature an enzyme making it unusable. pH levels also affect enzyme activity. Every cell has an ideal temperature and pH

pH, temperature, substrate concentration and enzyme concentration influences the rate of reaction

Enzymes operate best under a tight, optimal range of pH values. Extreme pH can seriously affect enzyme activity, so it is little wonder that big changes in pH can slow down enzyme activity. Extreme changes can often irreversibly inactivate and denature an enzyme.
