Which enzyme breaks down starch during digestion?

• A. Lipase
• B. Lactase
• C. Amylase
• D. Trypsin

Answer: (C)

Verified step by step guidance

1. Understand that starch is a polysaccharide composed of glucose units linked together, and it requires specific enzymes to be broken down into simpler sugars during digestion.
2. Identify the function of each enzyme listed: Lipase breaks down lipids (fats), Lactase breaks down lactose (a sugar found in milk), Trypsin breaks down proteins, and Amylase breaks down starch.
3. Recall that amylase is the enzyme responsible for catalyzing the hydrolysis of starch into smaller carbohydrate molecules like maltose and dextrins.
4. Recognize that amylase is produced in the salivary glands (salivary amylase) and pancreas (pancreatic amylase), playing a key role in carbohydrate digestion.
5. Conclude that among the options given, amylase is the correct enzyme that breaks down starch during digestion.
