Answer:

All of the above

Explanation:

Digestion or breakdown of food in our body can either be physical/mechanical or chemical/enzymatic. As rightly stated in this question, the manual breakdown of food by the teeth is not enough, chemical digestion must occur via the aid of proteinous substances called ENZYMES. Enzymes, which are secreted by certain organs in the body, do the following:

- They speed up the rate of chemical reactions by lowering the activation energy needed for the chemical process, allowing more productivity.

- Enzymes help break down various sugars that can then be absorbed e.g amylase helps break down starch, proteases break down proteins, lipases break down lipids etc.
