8.1 Overview of Photosynthesis Photosynthesis converts solar energy into chemical energy. Organisms that carry on photosynthesis are called autotrophs.
AP Biology Photosynthesis: Variations on the Theme.
Photosynthesis. Review the following terms:  Autotrophs and heterotrophs  The structure of chloroplasts and cell membrane  Electron transport chain.

USING LIGHT TO MAKE FOOD
The Dark Reaction - - light-independent - - energy stored in ATP and NADPH (from light reaction) is used to reduce CO 2 to sugar.
HBio: Photosynthesis.
Autotrophs : self feeders, producers, produce organic molecules from CO 2 ◦ Photoautotrophs: light energy ◦ Chemoautotrophs: oxidize inorganic compounds.
