Cell Respiration


Cellular respiration is the process by which the chemical energy of "food" molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.

ATP process

Since most textbooks provide abundant details of the chemical reactions in respiration, this tutorial will focus on how the chemical energy in glucose is converted into ATP and where respiration occurs in the cell.
