BIO 311C Lecture Notes - Lecture 13: Light-Dependent Reactions, Light-Independent Reactions, Chemiosmosis
Document Summary
E ciency = how much produced divided by how much put in. 6co2 + 6h20 + atp -(light)> 6c6h12o6 + 6o2. Photosynthesis: an anabolic endergonic process that uses light energy. Autotrophs: make their own foods photoautotrophs use light as energy source and inorganic carbon source of. Chlorophyll molecules located in thlyakoid membranes have mg+2 in the center. Pigments harvest energy (photons) by absorbing certain wavelengths (blue 420nm and red 660nm are most important) Absorbs additional wavelengths and transfers that energy to chlorophyll for use in photosynthesis. Anthocyanins absorb blue, blue-green, green light and uv. Two main parts (rxn: light reaction (light dependent reaction) stores energy from solar power (photons) in the form of atp and nadph2, calvin cycle (light independent reaction aka carbon fixation) uses energy (atp and. Nadph) from light rxn to make sugar (glucose) The light reactions and chemiosmosis: takes place in the thylakoid membrane.
