Overview 60 02 + 6H20 - C4H 1206 + 602 of Photosynthesis There are two phases of photosynthesis ? . Phase 1 : the light- dependent reactions where light energy is converted into chemical energy CATP & NADPH CLAY . Phase 2 : the light independent where the ATP and NADPH make glucdos Phase one : Chloroplasts Light Reactions ( light dependent ) [thylakoids = flattened saclike membranes that are arranged in stacks grang = stacks of thylakoids Stroma = fluid filled space outside grand (light-independent ) chlorophyll A is most Pigments plastS necessary for photosyn. pigments = light- absorbing colored molecules found in thylakoids membranes of chloro the major light absorbing pigments in plants are (chlorophyllis. ALB the most light cartenoids)= pigment which reflects yellow orange and reds . unlorophyll babsorbs there are many different types of pigments because they all differ in ther ability to absorb light making a wider range of visible light possible NADA = electron carrier Electron Transports (ETC) NADPH = electron storage . photosystem I all contain light - absorbing pigments and proteins that play important roles in the light reactions photosynthesis to occur ) ( this breakdown of water is essential for . the hydrogen needed I. light energy excites electrons coming in photosystem Il. The light energy in ETC comes from split splits into pill of, cases a Hzo molecule to split, releasing an electron into electron Of HZO transport system , a Hion ( proton) Into thylakoid space and Oz as a waste (HD ) 2 . The excited electrons move from photosystem Il to an electron - acceptor molecule in the thylakoid membrane - Photosystem 1 3. Next, the electron - acceptor molecule transfers the electrons along a series of electron carriers to photosystem 1 4. In the presence of light, photosystem I transfers the electrons to a protein called ferradoxin . The electrons lost by photosystem lane replaced by electrons shuttled from photosystem Il 5 . Finally. femodoxin transfers the electrons to the electron carrier NADP,* forming the energy-storage molecule NADPH ....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
