Amylase enzyme acts on the `-`

Options

A. Starch
B. Protein
C. Fat
D. Cane sugar

Answer

**Step-by-Step Solution:**

1. **Identify the Enzyme**: The question asks about the enzyme amylase. It is important to know what type of enzyme amylase is and where it is found in the human body.

2. **Location of Amylase**: Amylase is primarily found in saliva, where it is referred to as salivary amylase. It is also present in the pancreas as pancreatic amylase.

3. **Substrate of Amylase**: The main substrate that amylase acts upon is starch. Starch is a polysaccharide and a type of carbohydrate.

4. **Action of Amylase**: Amylase catalyzes the hydrolysis of starch into simpler sugars. Specifically, it breaks down starch into maltose, which is a disaccharide.

5. **Optimal pH**: The activity of salivary amylase occurs optimally at a pH of around 6.8, which is slightly acidic to neutral.

6. **Conclusion**: Therefore, the correct answer to the question is that amylase acts on starch.

**Final Answer**: Amylase enzyme acts on starch.
