What is effect of temperature on an enzyme?

Answer 1

Many of the enzymes in our bodies work best at body temperature. At significantly lower temperatures the substrate molecules do not have enough kinetic energy for the reaction to take place even in the presence of the enzyme. At body temperatures significantly higher than normal, the enzyme will not work well because the kinetic energy from the molecules in the solution containing the enzyme is so high, that the enzyme's shape is pulled apart to the point that the enzyme is not able to properly function.

Indeed the enzyme's structure may be so disrupted or denatured that the enzyme molecule cannot return to its original shape. Indeed the danger of high fevers stems in large part from the potential damage to enzymes and other proteins from the high temperature. The optimum performance of most human enzymes is at about 37o celcius, or the temperature of the human body. Exposing enzymes to elevated temperatures can cause them to denature, which basically means they will no longer be functional. Enzymes are more active at a specific temperature. At higher temperatures they get denatured, so their structure breaks down. Same effect as pH. At lower temperatures they become inactive, in this case when they reach their optimum temperatures, they will become active again.
temperature directly affects the rate of enzyme activity.On every 10 degree Centigrade rise in temperature,rate of enzyme activity doubles.but temperature affects up to its optimum range.For example:optimum temperature range of human is 37 degree centigrade.beyond this level of temperature,it can destroy the enzyme's structure and enzyme can be denatured due to fast vibration among its molecules which can lead to the bonds to break

Answer 2

Enzymes are designed to operate at certain temperatures. If the temperature varies it can either slow down the reaction rate of if it gets too high it can denature the enzyme making it unable to ever catalyze a reaction.

Answer 3

That depends on the temperature and the enzyme. We can break it down into 2 discreet parts:

1. Generally speaking, if heat is increased, energy is increased and the energy of the reactants will be higher (more collisions will occur) and the speed of the reaction will increase accordingly. This works as long as the enzyme remains intact.

2. If the temperature is too high for the enzyme, denaturation of the enzyme can occur, and if the heat is severe enough, the enzyme will be completely and irreversibly denatured. Denaturation occurs as heat starts breaking bonds within the enzyme structure, leading to loss of structure (tertiary and secondary), and ultimately function.

Answer 4

Each enzyme has its ideal temperature. This is the temperature at which it functions optimally (i.e has maximum activity). At temperatures higher or lower than the ideal temperature, there is a marked decrease in activity. As the temperature deviates further away from the ideal temperature, there is a complete loss of activity.

Answer 5

If the temperature is high the enzyme gets denatured .. if too low it gets inactive
