The Mitochondrion
This small body within the living cell is the site of the chemical events that supply energy to the cell. The molecular architecture that underlies this function has recently been revealed in detail

The Synthesis of Fat
When the way in which fat molecules are broken down was worked out, it was assumed that they are built up by the same steps in reverse. Now it has been found that the synthetic process is quite different

Biological Oxidation
How does the living cell "burn" carbohydrates and fats? It does so by means of an intricate web of chemical reactions which have been localized in the minute intracellular particles called mitochondria

The Metabolism of Fats
Together with the metabolism of sugar it provides the bulk of animal energy. Its key is the oxidation of fatty acids, a full knowledge of which has been obtained only this year

Enzymes in Teams
Biochemists have traditionally labored to isolate and observe individual enzymes. The author describes significant new work which indicates that these biological catalysts act in concert
