Temperature - too cold the enzyme will still work but slowly, too hot and the enzyme will become denatured . As temperature increases, the kinetic energy of the molecules increases so they move around more, meaning that there are more collisions between the enzymes and substrate molecules and therefore more reactions.
pH - different types of enzymes work best in different pH environments. A change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrate) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the substrate.
enzyme and substrate concentration - how many there is of each. Changing the concentrations of enzyme and substrate concentrations will affect the number of collisions between them and therefore the number of reactions.
enzyme inhibitors - these are molecules which bind to enzymes, reducing their activity (many drugs are enzyme inhibitors).
co-factors - these are chemical compounds which bind to enzymes and which are needed by the enzyme to work on substrate molecules. They are often called helper molecules.

What are some environmental enzyme factors?
Enzymes are catalysts that speed up chemical reactions. Some environmental factors that can affect enzyme activity are temperature and pH levels.
What affect does too much substrate have on the rate of an enzyme reaction?
The enzyme becomes saturated by the substrate and enzyme activity plateaus.
What factors affect the activity of enzymes?
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.
What factors affect the rate of enzyme activity?
-Heat, temperature, &pHtemperature, pH level, concentration of enzyme, concentration of substrate( my sec.1 science book)
Temperature and can affect enzyme activity?
Ph level, enzyme concentration, substrate concentration etc
What environment factors can affect the activity of an enzyme?
temperature
How do enzyme factors affect enzyme activity?
Ph level accelerates enzymes and temperature slows the process down
Is there any Procedure in enzyme and factors that affect enzyme activity?
pH, temperature, substrate concentration and enzyme concentration influences the rate of reaction
What are some environmental enzyme factors?
Enzymes are catalysts that speed up chemical reactions. Some environmental factors that can affect enzyme activity are temperature and pH levels.
What modify's the rate of enzyme activity.?
Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activator
How do factors such as temperature and pH affect enzyme activity?
By simply afecting the bonds ( hbonds . ionic bonds and hydrophobic interactions )
What are factors affecting enzyme activity?
Concentration ( enzyme to substrate ), temperature and pH.
What are 3 factors that affect the speed of an enzyme catalyzed reaction?
3 factors that affect the speed of an enzyme catalysed reaction are: .Temperature .Enzyme Concentartion .Substrate concentration
Discuss factors which affect growth and development ifarm animals?
what are the human factors that affect growth and development what are the human factors that affect growth and development
What are the four factors that effect enzyme activity?
temperature, pH, concentration of enzymes, and concentration of substrates.
What affect does too much substrate have on the rate of an enzyme reaction?
The enzyme becomes saturated by the substrate and enzyme activity plateaus.
Does freezing a enzyme affect it?
When an enzyme is frozen, it only slows down activity. Unlike boiling an enzyme, it does not stop it from working.
