Question

enzyme are protected at high temperature by a) ice crystal b) supercooling c) freezing tolerance d) heat shock protein​

Answer 1

Answer:

D .heat shock proteins

Answer 2

Enzymes are protected at high temperatures by a) ice crystal.

Explanation:

• At high temperatures, most of the enzymes are inactivated by aggregations at hydrophobic sites which are exposed to denaturation.
• Isolating denatured enzymes through hydrophobic interactions with other material is an important method to prevent enzymes from aggregation.
• Enzymes also become inactive at very low temperatures, thus both high and low temperatures alter enzymatic activity.
• Freeze thaw protection which are few groups report inhibition or slowing of ice crystal formation by additives that may prevent enzyme damage.
• Hence, the correct answer among all the options is option a) ice crystal.
