BIOL-UA 22 Chapter Notes - Chapter 12: Photophosphorylation, Leaf, Covalent Bond
Document Summary
12. 5 photosynthesis and light-absorbing pigments photosynthesis occurs in chloroplasts a specific type of organelle that is only found in leaf cells chloroplasts capture the energy of the sun and convert it into chemical energy in form of atp and. Thylakoid membranes in chloroplasts are the sites of photosynthesis in plants chloroplasts lens bounded by two membranes that don"t contain chlorophyll and do not participate directly in generation of. Three of the four stages in photosynthesis occur only during illumination photosynthesis occurs in four stages. 4. absorption of light, generation of high energy electrons and o2 formation electron transport and generation of a proton-motive force synthesis of atp carbon fixation a. b. stages 1-3 are light dependant reactions stage 4 is light independent. Absorption of light, generation of high energy electrons and o2 formation initial step is absorption of light by chlorophylls to proteins in thylakoid membranes. Electron transport and generation of a proton-motive force.
