17 Photosynthesis first converts light energy into ATP & NADPH. Then, ATP & NADPH are used to make glucose. Sunlight ATP & NADPH Glucose ©2015 Science Island

19 NADPH is a high energy electron carrier that is used to help turn CO2 into glucose. ©2015 Science Island

21 The stage of photosynthesis that actually produces sugar is the Calvin Cycle. Image is public domain. ©2015 Science Island

Where do the light reactions occur? In the thylakoid membrane 22 Where do the light reactions occur? In the thylakoid membrane Where does the Calvin Cycle occur? In the stroma ©2015 Science Island

24 The Light Reactions start when a pigment molecule in Photosystem II absorbs a photon of light which excites one of the pigment’s electrons. ©2015 Science Island

25 An excited electron is passed from PSII to an electron transport chain on its way to PSI. ©2015 Science Island

27 Chemiosmosis is the diffusion of ions through a semi-permeable membrane. This diffusion through an ATP Synthase molecule produces ATP from ADP. ©2015 Science Island

28 Photosystem I passes a light-excited electron to a short electron transport chain which generates NADPH. ©2015 Science Island
