Lesson Overview. 8.1 Energy and Life. THINK ABOUT IT. Homeostasis is hard work. Organisms and the cells within them have to grow and develop, move materials around, build new molecules, and respond to environmental changes. What powers so much activity, and where does that power come from?.

8.1 Energy and Life
8.2 Photosynthesis: An Overview
What is the purpose of the LDR’s?
Light dependent reactions use energy from sunlight to produce oxygen and convert ADP and NADP+ into energy carriers ATP and NADPH
Where does this happen?
3.Photosystem I: The electron are “re-charged” by pigments absorbing energy from the sunlight!
4. NADP+: These charged E’s now move down the rest of the chain and are transferred to waiting NADP+ forming NADPH.
5.ATP Synthase: H+ build in concentration within the space. This concentration and increasing charge forces ions through the ATP synthase which act as a turbine. As the ions pass the energy created produces ATP from ADP.
