Question

1. What is the metabolism process by which carbohydrates are used for energy? How do lipids and proteins differ?

2. What are the byproducts of each process noted above? How does the body get rid of the byproduct?

3. What are the main enzymes that break down carbohydrates, proteins and lipids?

Answer 1

1)

• The process of carbohydrate metabolism is glycolysis.
• In this pathway glucose is converted to pyruvate or lactate.
• All the reactions takes place in cytoplasm.

Protein and lipids are molecules that are essential for growth and developement.

• the difference between lipids and proteins is :
• protein contains aminoacids where as lipids containd fattyacids and glycerol

2)

• The byproduct of Glucose metabolism are Pyruvate or lactate
• and also carbondioxide and water.

3)

• Amylase enzymes breakdown carbohydrates
• Lipase enzymes breakdown lipids
• Protease enzymes breakdown protein
