You mean heating the enzymes? heating to a certain degree increases their rate of catalytic activity, until about 30-40 degrees Celsius. However if you continue heating, the enzyme's basic structure will be deformed (it changes shape), and since structure is essential to function, the enzymes activity will be reduced. that happens around 60-70 degrees Celsius, but it is different in various organisms.

∙ 9y agoEnzymes serve as catalysts for reactions. they must come into contact with the reactants in order to form the product. At freezing temperatures, there is insufficient movement of the atoms and molecules to bump into each other and react. Enzyme activity will increase as temperature increases until a certain point when production drops off. Most enzymes are proteins which will denature at excessively high temperatures. Very few enzymes can function at boiling.

What is varied when tested the effect of pH enzyme activity?
The pH is varied to effect, by its affect, this test.
How does initial concentration of substrate effect enzyme activity?
At low concentration of substrate , rate of enzyme action is directly proportional to conc. of substrate .
What is the effect of pH upon the relative enzyme activity?
Different enzymes work best at different pH. This is refered to as the ideal pH for the enzyme. For example, the digestive enzyme trypsin works best at an acidic pH while alkaline phosphatase works best at a basic pH. Therefore, enzyme activity varies with pH and this variation depends on the enzyme being studied
What switchs on enzyme activity while what can switch off or reduce enzyme activity?
activators; inhibitors
What is the effect of phosphorylation on enzyme activity?
Phosphorylated enzymes may be more or less active than non-phosphorylated enzymes
What is the effect of hydrochloric acid on the enzyme activity?
Denature enzyme activity
What is the effect of cold temperatures on enzyme activity?
Cold temperatures have a drastic effect on an enzyme's activity level. Cold temperatures usually dramatically slow down an enzyme's activity.
What is varied when testing the effect of pH on enzyme activity?
pH
What is varied when tested the effect of pH enzyme activity?
The pH is varied to effect, by its affect, this test.
What two internal body conditions effect enzyme activity?
temperature and pH
How does initial concentration of substrate effect enzyme activity?
At low concentration of substrate , rate of enzyme action is directly proportional to conc. of substrate .
What is the Effect of mineral and vitamin deficiency on enzyme activity?
many vitamins and minerals play crucial roles in many metabolisms as coenzyme or cofactor. Deficiency of those lower the related-enzyme activity.
What can you do to regain the activity of the enzyme?
The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity
What are the effects of physical activity on enzyme activity?
Physical activity can alter the shape of enzyme which can cause damage or may the enzyme become inactive
What is the effect that lowering the temperature would have on the rate of enzyme activity explain?
It would lower the speed of the reaction but will do no harm to the enzyme.
What is the effect of pH upon the relative enzyme activity?
Different enzymes work best at different pH. This is refered to as the ideal pH for the enzyme. For example, the digestive enzyme trypsin works best at an acidic pH while alkaline phosphatase works best at a basic pH. Therefore, enzyme activity varies with pH and this variation depends on the enzyme being studied
9th grade level biology question. Temperature and what can affect enzyme activity?
effect of ph and concentration of subtrate
