Cell organization

Classified as eukaryotes or prokaryotes

Viruses

Viruses are merely genetic information surrounded by a coat of protein. They require most cells to reproduce.

Carbohydrates, fats, and proteins can ask be used as fields in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.
