8.1 Overview of Photosynthesis
Photosynthesis is a process that captures sunlight and converts it into chemical compounds used by organisms to power their metabolism.
Main Structures and Summary of Photosynthesis
In multicellular autotrophs, the main structures that allow photosynthesis to take place include chloroplasts, thylakoids, and chlorophyll.
The Two Parts of Photosynthesis
Light-dependent and light independent-reactions are two successive reactions that occur in photosynthesis.
8.2 The Light-Dependent Reactions of Photosynthesis
What Is Light Energy?
All electromagnetic radiation, or light energy, travels at a particular wavelength and carries a certain amount of energy.
Absorption of Light
Pigments, like chlorophyll and carotenoids, absorb and reflect light at a certain region of the electromagnetic spectrum.
How Light-Dependent Reactions Work
Light-dependent reactions, which take place in photosystem I and II, convert solar energy into NADPH and ATP.
