Multiple Choice Question______ chemically digests denatured proteins in the stomach into smaller fragments.Multiple choice question.LipaseLysozymePepsinAmylase

The correct answer is Pepsin.

Step 1: Understand the question. The question is asking which enzyme chemically digests denatured proteins in the stomach into smaller fragments.

Step 2: Review the options. The options given are Lipase, Lysozyme, Pepsin, and Amylase.

Step 3: Match the options with the question.

• Lipase is an enzyme that the body uses to break down fats in food so they can be absorbed in the intestines, so it is not the correct answer.
• Lysozyme is an enzyme that breaks down bacterial cell walls, so it is not the correct answer.
• Pepsin is an enzyme that breaks down proteins into smaller peptides (that is, a protease). It is produced in the stomach and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food. So, Pepsin is the correct answer.
• Amylase is an enzyme that helps change starches into sugars, so it is not the correct answer.

So, the correct answer is Pepsin.
