BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The intra-and intermolecular bonds that hold proteins in their secondary and tertiary structures are disrupted by changes in temperature and pH. This affects shapes and so the catalytic activity of an enzyme is pH and temperature sensitive.

Detailed explanation-2: -Enzymes function at an optimal pH where the highest activity can be observed. Outside this pH value, the activity of the enzyme decreases, and the rate of an enzyme-catalyzed reaction slows down.

Detailed explanation-3: -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.
