Document Summary

Process of using solar energy and water to produce food. Takes place in the thylakoid: happens only during the day time. Sunlight and water are used to produce atp and nadph. Takes place in the stroma (fluid outside the thylakoid: happens all the time. Be able to explain what happens during this process. Energy from the electrons moving down the electron transport chain creates a proton gradient across the thylakoid membrane. Lower levels of sunlight cause chlorophyll to break down. Accessory pigments become more visible during the fall: be able to explain each step of the light-dependent reaction. Sunlight energy is absorbed by chlorophyll in psii and psi. Electrons from psii enter the electron transport chain: water is split to re-supply electrons to psii. Electrons from psi enter the electron transport chain and are donated to nadp, producing nadph: be able to explain each step of the calvin-benson (light-independent reaction). Understand which steps require energy and how much.
