Question

unit 2 quiz 2
the major function of digestive enzymes is the ~
o regulation of the rate of chemical reactions
o transport of substances within organisms
o synthesis of cell walls and membranes
o excretion of harmful waste materials

Explanation:

Enzymes are biological catalysts. Digestive enzymes specifically act on food substances in the digestive system. Their main role is to speed up (catalyze) the chemical reactions involved in breaking down large food molecules (like proteins, carbohydrates, and fats) into smaller, absorbable units. This is in line with the concept of enzymes regulating the rate of chemical reactions. Transport of substances within organisms is mainly the role of systems like the circulatory system. Synthesis of cell walls (in plants) and membranes involves other cellular processes and molecules. Excretion of harmful waste materials is the function of excretory organs like the kidneys (in humans).

Answer:

regulation of the rate of chemical reactions
