The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Starch**: Starch is a polysaccharide made up of glucose units. It is a complex carbohydrate that needs to be broken down into simpler sugars for digestion. 2. **Digestion of Starch**: The digestion of starch begins in the mouth. Saliva contains an enzyme called salivary amylase, which is responsible for breaking down starch into simpler sugars. 3. **Percentage of Digestion**: Approximately 30% of starch is digested in the mouth due to the action of salivary amylase. This enzyme converts starch (a polysaccharide) into maltose (a disaccharide). 4. **Location of Digestion**: The question specifically asks where this 30% digestion occurs. Since it takes place in the mouth, we can conclude that the answer to the question is the mouth. 5. **Further Digestion**: Although 30% of starch is digested in the mouth, the remaining starch continues to be digested in the stomach and small intestine, where other enzymes further break it down. **Final Answer**: About 30% starch is digested in the mouth. ---
