How does temperature effect enzyme action?

Answer 1

The enzyme activity increases as the temperature rises due to the substrates colliding with the enzymes' active sites more frequently at higher temperatures. However, each enzyme has an optimum temperature as high temperatures denature enzymes.

Answer 2

Enzymes generally have an optimal temperature range and increasing or deceasing away from this range decreases the effectiveness of a protein, but this process is reversible. Conformational changes are important to the function of many enzymes and thermal energy tends to influence them greatly, low temperature limit them. Increasing temperature can enhance the reactions process up to a point.

Enzymes are proteins and when proteins are heated to above their temperature threshold they begin to change their 3d structure and become ineffective. The same happens to enzymes, those enzymes can no longer work properly when their 3d structure is altered due to the increase in temperature.

Answer 3

Each enzymes has its own unique property. So an enzyme catalyses its specfic activity in a very specific temperature,so called as optimum temperature below or above that the activity will be less.

Answer 4

As temperature increases, activity of an enzyme tends to increase up until a certain temperature (usually around 60 degrees Celsius) after which the enzyme is denatured and its activity is zero. Optimum temperature (where activity is highest) is usually around 35-40 degrees Celsius.

The graph of enzyme activity versus temperature will therefore be a bell curve with a peak around 40 degrees.

Answer 5

it depends what enzyme your talking about. each one is different but generally speaking, enzymes will not work at either very low temperatures (ie 0-5 degrees Celsius) or very high temperatures (usually anything over 45 degrees Celsius). at high temperatures they will "denature" which means the shape of the enzyme will change and so will no longer work. each different enzyme though has a specific "optimum temperature" (the temperature at which the enzyme will preform most efficiently). if it is an enzyme found in the human body, the optimum temperature will usually be body temperature....around 37 degrees Celsius.

Answer 6

Enzymes are sensitive to temperature. They change in size according to temperature. Say you cook a piece of meat, when it is done cooking, the amount of enzymes are much much lower because many died from the heat. If the enzymes in the body get too cold, they shrink and die from lack of resources to supply the cell. If they get too large, then they are too spread out and need too many resources and die.

Answer 7

the temperature can disort the enzyme causing it to not be able to do the function that it was originally structured to do.

Answer 8

maybe if the temperature increases the enzyme will start to process in another way

Answer 9

Temperature effects enzyme activity because in the winter your skin dries up and in the summer the sweaty stuff makes more rashes.
