Learners review a graphic summary of the three series of reactions that occur during cellular respiration and the net energy (ATP) yield of that process.

In this animated and interactive object, learners examine ventilation, external and internal respiration, and gas transport.

In this screencast, learners categorize different metabolic activities as catabolic or anabolic and follow a glucose molecule through the processes of glycolysis, aerobic respiration, and fermentation.
