Outline for Chapter 23: Carbohydrate Metabolism

Chapter 22

1.  Digestion of carbohydrates

2.  Glucose metabolism: (a) Glycolysis, (b) Glycogenesis, (c) Pentose phosphate pathway, (d) Glycogenolysis, (e) Gluconeogenesis.  Learn the names of intermediates and the enzymes that catalyze each step.

3.  Production of ATP and NADH/H+

4.  Entry of other sugars into glycolysis

5.  Pyruvate metabolism: (a) Aerobic conditions pyruvate is converted to acetyl-SCoA; (b) Anaerobic conditions pyruvate is reduced to lactate; (c) In yeast pyruvate is converted to ethanol.

6.  Energy output from complete catabolism of glucose

7.  Regulation of glucose metabolism: Hypoglycemia (low blood sugar); Hyperglycemia (high blood sugar).  Role of insulin and glucagon.

8.  Effects of fasting and starvation

9.  Diabetes mellitus
