Detailed explanation-1: -This optimal temperature is usually around human body temperature (37.5 oC) for the enzymes in human cells. Above this temperature the enzyme structure begins to break down (denature) since at higher temperatures intra-and intermolecular bonds are broken as the enzyme molecules gain even more kinetic energy.
Detailed explanation-2: -Most enzyme functions are performed at 37∘C in humans because the enzymes are able to retain its structure at that temperature, allowing it to break down complex molecules efficiently.
Detailed explanation-3: -The optimum temperature in most enzymes is around 37 degrees Celsius. When the temperature increases, however, the enzymatic activity decreases. This is because higher temperatures tend to denature proteins, which in turn causes them to lose their functionality.
Detailed explanation-4: -The optimum working temperature of an enzyme is a because of the interplay between chemistry, where higher temperatures equal faster reactions, and biology, where proteins become denatured at certain temperatures.
