Digestion and Enzymes

Task 1:
Use RDA tables to explain why the dietary energy requirements of young children, adolescents, elderly people and pregnant and lactating women can vary.
Giving examples of different nutrients, explain why the dietary requirements may vary for people of different ages, gender and occupations.

Task 2:
Explain what happens to a meat sandwich as it passes through the digestive system. In your answer you must include reference to mechanical and chemical digestion, ingestion, digestion, absorption, assimilation, egestion and the structure and function of the alimentary canal. When explaining absorption, make sure that you explain the structure and function of villi in this process. Ensure that you include the location and roles of the key digestive enzymes.

Task 3:
Explain the characteristics of enzymes and (using named examples), the
lock and key theory of enzyme action. Include in your answer, an explanation of the
role of enzymes in both catabolic and anabolic reactions.
