Document Summary
Photosynthesis: only way energy enters biosphere (energy/sunlight, measurement of chlorophyll is measurement of photosynthetic organisms, 50% oceanic, 50% terrestrial, temperature doesn"t have much to do with distribution of photosynthetic organisms, ex. Antarctic have lots even though it is cold, but the atlantic which is warm isn"t: photosynthesis: changes carbon dioxide to glucose using light energy, no electrons in co2, carbon-hydrogen bonds have electrons and energy! The two phases- spatial relationship: takes 2 electrons to do something to adp and nadp, need energy and electrons to run endergonic process. Need to know mitochondrial structure and choloplast structure: outer membrane, inner membrane, box: stroma, thylakoid membrane, inside t membrane: is thylakoid lumen, nothing eukaryotic about photosynthesis. Note u"ve a shit ton about this topiclook it up on youtube and text or else ur fucked: takes energy to make atp, energy comes from chemiosmosis. Nadph: h2o has a very positive redox potential.
