Question

Which substance helps break down starch during digestion?

Answer 1

Amylase

Explanation:

Amylase is an enzyme which breaks down starch into maltose. It is found in the mouth and in the Small Intestines. The amylase breaks the bonds to form smaller molecules( simple sugar). It is then absorbed and used by the cells for aerobic respiration( cellular respiration).

Here is a video of an enzyme demonstration I like to share with my students. The video shows how an enzyme (salivary amylase) present in our saliva (spit) can aid in the process of digestion by acting on starches present in the foods we eat.
