Document Summary
Only occurs in plants (some protists, and bacteria) they are photosynthetic organisms. It"s a process that: traps light energy and stores it as chemical energy, energy stored in bonds of organic molecules, this requires co2 and h2o produces glucose and o2. 6 co2 + 6 h2o + energy c6h12o6 (glucose) + 6 o2. Chloroplasts: located in cells of mesophyll, small in size, double membrane organelles containing, stroma (-fluid, grana (-stacks of thylakoids, thylakoids (-interconnected membranous sacs, contain pigments to absorb light (e. g. chlorophyll) Photosynthetic pigments in plants (a table in ppt) Process of photosynthesis: 2 stages of reactions. Electron from etc ii enters ps i: photons absorbed by pigment clusters. Carbon fixation: capture of carbon from co2. Regenation of rubp: series of enzyme catalyzed reactions, requires atp, 5 g3p 3 rubp, rubp molecules used in carbon fixation, entire calvin cycle repeats.
