Through interactive learning exercises, students examine the different definitions of energy and how enzymes regulate how the energy is stored and used during cellular respiration. They also take a close look at photosynthesis to learn...

A set of virtual experiment assignments where students investigate the process of photosynthesis and how it varies with different types of plants. They will change experimental conditions to see how different factors affect the rate of...

Learn about the three stages of the Calvin Cycle reactions: carbon fixation, reduction, and regeneration of the starting molecule. See how the products of the light reactions, ATP and NADPH, are used to fix carbon into sugars in this cycle.

Photorespiration is a wasteful pathway that competes with the Calvin cycle. Explore why photorespiration happens, when it's most likely to take place, and how it actually works.
