Khan Academy
Khan Academy: The Light Dependent Reactions
Article explores the light-dependent reactions as they take place during photosynthesis in plants. Traces how light energy is used to make ATP and NADPH and explains photosystems and electron transport chains.
Khan Academy
Khan Academy: The Calvin Cycle
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.
Khan Academy
Khan Academy: Photorespiration
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.
Khan Academy
Khan Academy: C3, C4, and Cam Plants
Article takes a close look at how the C4 and CAM pathways help reduce photorespiration.
