BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Answer and Explanation: The correct answer: The factor which does NOT affect enzyme activity is d. Free Energy.

Detailed explanation-2: -Several factors affect the rate at which enzymatic reactions proceed-temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

Detailed explanation-3: -Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.

Detailed explanation-4: -Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.
