Resource examines how non-glucose molecules such as carbohydrates, proteins, and lipids enter the cellular respiration pathway. Also, looks at the use of cellular respiration intermediates for biosynthesis.

Introduction to redox in cellular respiration. Provides an overview of how cells break down fuels and looks at some of the electron transfer reactions that are key to this process.

A good general review of aerobic and anaerobic respiration. Good graphics and good embedded vocabulary links.

The electron transport chain plays an important role in cellular respiration and photosynthesis and provides a biochemical pathway for the generation of ATP. The process is described here.

This site describes cellular components involved in light reaction and describes steps involved in photosynthesis.

Article presents an in-depth overview of oxidative phosphorylation which provides most of the ready chemical energy (ATP) used by the cells in your body.
