BIOMOLECULES AND ENZYMES

Detailed explanation-1: -This flexibility is essential to how enzymes bind to other molecules and cause chemical reactions to happen on those molecules. Lowering the temperature slows the motion of molecules and atoms, meaning this flexibility is reduced or lost. As the temperature decreases, so does enzyme activity.

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: -Why will most enzyme-controlled reactions occur slowly at a low temperature? A lower temperature means the molecules have less elastic energy, so they do not bind together as frequently. A lower temperature means the molecules have more kinetic energy, so they collide frequently.
