Document Summary

Lecture 7 exam review: npp = gpp r. Food, fiber, energy: renewable energy (biomass, charcoal, wood, hydro or wind power, non renewable (fossil fuels of plants and minerals) Overview of global hanpp: humans appropriate about 1/3 of global primary production. History of photosynthesis: example of a mouse can stay alive in a jar if there is a plant in the jar, but not if there is no plant (oxygen) Antoin-laurent lavoiser: showed oxygen a product of respiration of plants. Photosynthesis: light limited portion, light saturation portion, photo inhibition portion, light compensation point shows where photosynthesis can be equivalent to respiration. Emerson and arnold: determined a linear relationship between plant pigment molecules and production of oxygen molecules, concept of photosynthetic unit. Chloroplasts: how photosynthesis is packaged within plants. Proton gradients: in light reactions, h+ gradients allow transport between intermediates and. Photosystems 1 and 2 and finally to atp synthase to produce atp.
