Metabolism and Nutrition

INTRODUCTION
1. Generalize the way in which nutrients are processed through the three major metabolic fates in order to perform various energetic and structural functions in the body.
CARBOHYDRATE METABOLISM
2. Review carbohydrate metabolism in the GI tract, liver and body cells.
3. Describe the controlled, facilitated entry of glucose into different cell types, and the means to capture and/or release it from specific cells.
4. Describe the processes of glycolysis (review in text), glycogenesis, glycogenolysis, and gluconeogenesis. Describe starting materials and end products and which hormones control each process.
LIPID METABOLISM
5. Explain the formation and removal of chylomicrons from blood.
6. Discuss how lipids are transported in blood.
7. Discuss the sources of cholesterol and indicate the concentrations that are considered as potential problems for coronary artery disease.
8. Describe how lipolysis breaks down the triglycerides into glycerol and fatty acids. Explain where glycerol enters carbohydrate metabolism. Describe how fatty acids undergo beta oxidation and where those products enter the carbohydrate metabolism pathway.
9. Describe ketogenesis and lipogenesis.
PROTEIN METABOLISM
10. Trace the general path of amino acid absorption and use by the liver and the body as a whole. List the hormones that have a role in controlling protein metabolism.
