D

Iodine

Text Solution

AI Generated Solution

The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Amylase**: - Amylase is an enzyme that plays a crucial role in the digestion of carbohydrates. It catalyzes the breakdown of starch into simpler sugars. 2. **Identifying the Substrate**: - The substrate for an enzyme is the substance upon which the enzyme acts. In the case of amylase, it specifically acts on starch. 3. **Types of Amylase**: - There are two main types of amylase: - **Salivary Amylase**: Secreted by salivary glands, it begins the digestion of starch in the mouth. - **Pancreatic Amylase**: Secreted by the pancreas into the small intestine, it continues the digestion of starch. 4. **Analyzing the Options**: - **Nucleic Acid**: Incorrect, as it is the substrate for nucleases, not amylases. - **Protein**: Incorrect, as it is the substrate for proteases, not amylases. - **Starch**: Correct, as it is the primary substrate for amylase. - **Iodine**: Incorrect, as it is a mineral and does not serve as a substrate for any enzyme. 5. **Conclusion**: - The correct answer is **starch**, which is the substrate for the amylase enzyme.

  • Arrange the steps of catalytic action of an enzyme in order and select the correct option I. The enzyme releases the products of the reaction and the enzyme is free to bind to another substrate II. The active site of enzyme is in close proximity of the substrate and breaks the chemical bonds of the substrate III. The binding of substrate induces the enzyme to alter its shape fitting more tightly around substrate. VI. The substrate binds to the active site of the enzyme
