Detailed explanation-1: -Psychrophiles have evolved by producing, among other peculiarities, “cold-adapted” enzymes which have the properties to cope with the reduction of chemical reaction rates induced by low temperatures.
Detailed explanation-2: -Lower temperatures lead to slower chemical reactions. Enzymes will eventually become inactive at freezing temperatures but will restore most of their enzyme activity when temperatures increase again, while some enzymes lose their activity when frozen.
Detailed explanation-3: -The working of enzymes is slowed down with the lowering of temperature, while higher temperatures destroy them. This flexibility is essential to how enzymes bind to other molecules and cause chemical reactions to happen on those molecules.
