Sweet
chew and swallow it. Our teeth help
us in cutting, chewing and grinding Tongue
food.

When we chew our food, the
complex particles of the food
break down in simple ones.
Chewing makes food easy to

digest.

When we chew food, it
becomes sweet in taste. Do
you know why?

The food seems sweet
because saliva from our
mouth gets mixed in it.

Glucose present in the food
makes it taste sweet because
when we chew food, the digestive enzymes present in saliva break down

complex food particles into simpler sugars, i.e., glucose.
Glucose gives energy to our body. Do you drink glucose during summer?

Have you seen a patient being given glucose through a drip in his arm? This
helps the patient to recover from weakness.
