Question

the function of mechanical digestion of food is to
○ a. break down enzymes so that they are able to function
○ b. expose more surface area for enzyme activity
○ c. decrease peristaltic action
○ d. break down food so that it can be absorbed immediately
the effect of ph rate of an enzyme catalyzed reation

Explanation:

Mechanical digestion, like chewing, physically breaks food into smaller pieces. This increases the surface - area to volume ratio of food particles, allowing enzymes to act more effectively. Enzymes don't need to be broken down to function (a is wrong), mechanical digestion doesn't decrease peristalsis (c is wrong), and food still needs further chemical digestion and absorption processes after mechanical digestion (d is wrong).

Answer:

B. expose more surface area for enzyme activity
