The Digestive Process Breaks Large Molecules into Small Molecules for Absorption

The digestive process breaks large molecules into small molecules for absorption. In animals

A) physical digestion always precedes enzymatic digestion because it increases the surface area for enzymatic attack.
B) digestive enzymes have a similar specificity to other enzymes. They are sensitive to pH temperature and operate on specific bonds only.
C) the process of enzymatic digestion is similar within groups and therefore there is little correspondence between the types of food an animal eats and the digestive enzymes it produces.
D) secreted enzymes are similar with some digestive enzymes acting only on specific bonds.
E) complete enzymatic breakdown of food involves the sequential secretion of different digestive enzymes along the length of the gut.
