Unformatted text preview: Cellular respiration glycolosis: Chapter 8: Photosynthesis Where does our energy come from?? Photosynthesis Conversion of solar energy into chemical energy All organic energy ultimately derived from P 6CO 2 + 12H 2 O C 6 H 12 O 6 + 6H 2 0 + 6O 2 The glucose we utilize for cellular respiration The Oxygen we use to breath Who performs photosynthesis? Cyanobacteria Blue Green Algae 7 Groups of Algae 7 More algae groups!!! All terrestrial plants Oh &$@!, Not more reactions! Light Reaction: Converts energy from the sun Converts NADP+ into NADPH Produces ATP Produces O 2 Carbon Fixation (aka Calvin cycle, aka dark reaction): Uses ATP and NADPH to make organic sugar Makes it from CO 2 C 6 H 12 O 6 (aka glucose) Chloroplasts Have duel membranes Stroma (interior fluid, Matrix of mitochondria) Thylakoid Inner membranes Flattened into stacks Contain chlorophyll et al. Granum Stacks of thylakoids Pigments Pigment Molecule that absorbs light Photon Particle of light Acts as a bundle, moves in a wave Photoelectric effect Removal of an electron from a molecule by light Photons power this reaction Absorption vs Reflectance...
