1. Gelatin is produced when collagen is broken into smaller molecules.

Name the chemical reaction that produces gelatin from collagen.

2. Explain how consuming gelatin can be useful in increasing collagen levels in the body. In your answer, identify any chemical processes involved.

b. Vitamin C is required for the production of collagen in the body.

What is the source of the vitamin C present in the body? Justify your answer.
