How do LOW temperatures interfere with enzyme activity?

Question

I know high temperatures cause denaturation and all that proverbial jazz.

Answer 1

slows enzyme reactions down

Answer 2

Enzyme activity is determined by their individual optimum level. High temperatures generally increase activity and will only cause denaturation when the temperature increases above their critical temperature. Low temperatures generally decrease activity or no reaction occurs at all.

Increases in the temperature of a system results from increases in the kinetic energy of the system. This has several effects on the rates of reactions.

1) More energetic collisions
2) The number of collisions per unit time will increase.
3)The heat of the molecules in the system will increase, increasing the internal energy of the molecules in the system

Lowering temperatures will hence do the opposite.

Answer 3

Temperature is actually the movement of the molecules. At lower temperatures, the movement of the enzyme molecules and substrate molecules slow down. So there is less chance for them to meet. Therefore, enzyme activity decreases. The higher the temperature, the higher the enzyme activity, up to a point when the enzyme starts to be denatured.

Answer 4

surely, an exceptionally dramatic replace in temperature or a transformation in the pH will denature an enzyme...which in certainty means that the enzyme will replace that is shape and not have the means to paintings effectively... the full theory in the back of enzymes is the lock and key approach.. if the important shifts its shape, it won't have the means to greater healthful the lock... good luck

Answer 5

Enzymes are always affected by temperature. They funtion best in 98.6 degrees fahranheit. HOwever, when put to low tempertures, enzymes slow down there activity.
