There are several factors that affect enzyme itself.
1. Temperature
As the shape specificity of the enzyme's active site is vital for any enzyme reaction, therefore an optimal temperature is important for enzymes. Enzymes will be inactive under low temperatures since it has too low kinetic energy to start the reaction or quickens the reaction. Alternatively, enzyme's structure and the shape of active site will changed in high temperature. Eventually, enzymes are denature and never can be used again.
2. pH value
As mentioned, the structure of enzyme is highly sensitive to the external environment, therefore pH value of the environment also has an effect on enzymes. Again, the shape of enzymes changed outside the range of pH value that suits particular enzymes. For instance, the optimum pH value for enzymes in stomach is around pH 2 whereas most are pH 7.
3. Presence of inhibitor
There are 2 types of inhibitor, one is non-competition inhibitor. These inhibitors will bind to the allosteric site (alternative site) of the enzymes that alters the shape of active site, therefore preventing the substrate from binding the enzymes and having reactions.

Below optimum point (usually 37 to 40C) not much kinetic energy thus less collision will happen, above it protein enzymes will be denatured by the rigorous molecular motions, thus ionic and hydrogen bonds that hold the 3 dimensional shape of enzymes are disrupted.
pH
Too much acidity or if the enzyme environment is too basic, intra and intermolecular bonds that holds the enzyme's 3 dimensional shape will be disrupted, thus denaturing the enzyme, and destroying its capability of fitting in or locking in to the substrate.
Inhibitors
Inhibitors are substances that bind to enzyme and decrease enzyme activity... look at the related link below.

Enzymes are affected by both pH and?
temperture.
How would reactions be affected if enzymes were not present in cell?
enzymes are the catalyst that aid the reactions taking place inside our bodies. if there were no enzymes, our metabolic processes would slow down to such a rate that we would not be able to survive.
Are the cell walls affected by temperature in the same way that the plasma membrane is?
Ribosomes, enzymes and cell membranes are all affected by temperature. The cell wall protects the cells that is why it is tough and flexible.
What are the three things that effect enzymes?
Following are the factors affectingenzymes:SalinityTemperatureInhibitorsAllosteric factorspH levelSubstate concentrationCatalystEnzyme concentration
What are 3 characteristics of enzymes?
Temperature/pH/Substrate Concentrate and Inhibitors
What aspect of chemical reaction is affected by enzymes?
The reaction rate is affected by enzymes.
What aspect of a chemical reaction is affected by enzyme?
The reaction rate is affected by enzymes.
Enzymes are affected by both pH and?
temperture.
What activity level are enzymes affected by?
Temperture
How are enzymes affected by environment?
As I know, enzymes can be found in all plants. If no enzymes could be found in plants, there was no life.
What characteristic of enzymes?
they are efficient. their action is affected by the environment. they are specific.
What are characteristics of enzymes?
they are efficient. their action is affected by the environment. they are specific.
How do pH levels affected enzyme?
It disrupts an enzymes shape and structure.
Substances that promote chemical reactions in living things but not affected by the reaction are?
enzymes
How would reactions be affected if enzymes were not present in cell?
enzymes are the catalyst that aid the reactions taking place inside our bodies. if there were no enzymes, our metabolic processes would slow down to such a rate that we would not be able to survive.
Why are so many varied phenotypes within a species such as human?
The phenotypes are affected by your enzymes since all metabolic activities of our bodies are down to enzymes.. Your Enzymes are proteins. They have been made from translation after transcription. Thus Your DNA got transcribed to make the enzymes.
What two types of enzymes exist in fat cells?
Fat cells, also known as adipocytes, have two types of enzymes, both of which are affected by insulin. The names of these two enzymes are pyruvate dehydrogenase and acetyl-CoA carboxylase.
