Answer 2

So Here Buddy I Am Adding The Answer You Requires...

Saliva contains an enzyme called as Amylase which break down Amylose in starch into Amylopectin.

Amylase cause hydrolysis reaction and breaks down the starch particles into smaller particles leading to final production of simple Carbohydrates.

Amylase enzymes secreted in saliva help break down starches into simpler sugar molecules that can be absorbed into the bloodstream. In this way, amylase activity influences blood glucose levels, which need to be maintained within an optimal range for good health.

Experiment To Show The Effect Of Saliva On Starch :-

1- Take 2 test tubes labelled A and B, where Tube A contains 1 Teaspoon Boiled Rice and Tube B contains 1 Teaspoon Rice which has been chewed for 3-5 minutes.

2- Add 4ml of water to both the test tubes and then 2-3 drops of idione solution to both the tubes.

Result :

The color of test tubes A changes to Bluish-Black color whereas the color of test tubes B remains Unchanged.

This Shows the Reaction of saliva on starch particles...

Hope It's Helps
