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: -Description. As the temperature is increased enzyme activity increases to a maximum value at the optimum temperature (around 37 oC for most human enzymes). As the temperature is increased above the optimum temperature enzyme activity decreases.
Detailed explanation-3: -Temperature: Enzymes work best when your body temperature is normal, about 98.6°F (37°C). As temperature increases, enzyme reactions increase. But if the temperature gets too high, the enzyme stops working. That’s why a high fever can disrupt bodily functions.
