Review Metabolism


By this time in your study you should have a pretty good knowledge of the individual metabolic relationships in carbohydrates, lipids, and protein. Hopefully, you have also begun to see that there are numerous interconnecting points between all three types of metabolism. This should be particularly evident in the considerations of diabetes, the amino acid transaminations, and the urea cycle.

As a further exercise in summarizing the metabolic interrelationships, you may be asked to do "road map" problems for pieces of the overall metabolism sequences.

A "road map" problem is merely the diagramming of a particular metabolic pathway. The pathways described should be at least as detailed as that shown on the graphic on the left. In all cases, the starting point is the ingestion of the particular food listed.

You should be able to diagram road maps for:
a) carbohydrate to CO2 and H2O
b) carbohydrate to lipid
c) protein to lipid
d) protein to CO2, H2O, urea
e) protein to glucose or glycogen
f) carbohydrate to glycogen
g) lipid to CO2 and H2O
h) lipid to protein
