BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The optimum temperature for most enzymes is about 98.6 degrees Fahrenheit (37 degrees Celsius). There are also enzymes that work well at lower and higher temperatures.

Detailed explanation-2: -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-3: -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-4: -Salivary amylase activity is tested at 37 degrees Celsius because the normal temperature of the human body is 37 degrees Celsius and the activity of enzymes is most optimal at this temperature.

Detailed explanation-5: -The physiological temperature, 37 °C, matches directly the natural condition of the enzyme and, compared with the other two assay temperatures, the enzyme develops there its highest activity, i.e. the lowest enzyme amounts are required (Figure 5A).
