BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Optimum temperature is the temperature at which enzyme activity is maximum. In humans, this temperature is 37.5oC that is same as the normal body temperature. A rise in temperature above 40oC results in denaturation of the proteins of enzyme.

Detailed explanation-2: -Because most animal enzymes rapidly become denatured at temperatures above 40°C, most enzyme determinations are carried out somewhat below that temperature. Over a period of time, enzymes will be deactivated at even moderate temperatures. Storage of enzymes at 5°C or below is generally the most suitable.

Detailed explanation-3: -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-4: -Optimum Temperature While higher temperatures do increase the activity of enzymes and the rate of reactions, enzymes are still proteins, and as with all proteins, temperatures above 104 degrees Fahrenheit, 40 degrees Celsius, will start to break them down.

Detailed explanation-5: -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.
