ABSTRACT
This brief and greatly simplified outline of the energy conversions within the cell is not intended to be an introduction to the study of biochemistry. Only the minimum of factual biochemistry to allow illustration of the broad principles and concepts has been included. The purpose is to give the reader with no biochemical background enough perception of the biochemical processes of the cell to help their understanding of nutrition. This short summary may also provide a useful overview for readers who have studied biochemistry. Certain nutritionally important observations should be clarified by this discussion, such as those listed below.
