Which of the following enzymes is found in saliva of human body which breaks down starch into simple sugar?

Amylase

The correct answer is Option (1) – Amylase

Out of the choices you provided, the enzyme found in saliva that breaks down starch into simple sugars is: Amylase

Here's why the other options are not found in saliva:

• Trypsin: This enzyme is produced by the pancreas and helps break down proteins in the small intestine.
• Pepsin: This enzyme is produced by the stomach and helps break down proteins in the stomach.
• Renin: This enzyme is produced by the kidneys and helps regulate blood pressure. It's not involved in digestion.

Amylase, specifically salivary amylase, is an important enzyme in the first stage of carbohydrate digestion. It starts breaking down complex carbohydrates like starch into simpler sugars like maltose as we chew our food. This process continues further in the small intestine with the help of other digestive enzymes.
