3. Other than energy provision, what other functions do carbohydrates have?

4. How are carbohydrates classified?

5. What are the consequences of lack of glucose in the body?

6. To keep glucose rates constant, in the fasting period, the body is able to produce this carbohydrate. How does the gluconeogenesis pathway occur?
