Document Summary

In all cases, hydrophobic tails avoid h2o & the heads interact with the water: micelle, hydrophobic tails in center, hydrophilic heads on outside, bi layer sheet, single layer, 2 molecules thick, hydrophobic tails interact in middle of layer or sheet, liposome (or spherical bi layer, website figure = liposome figure, related to bilayer, but circular, side view of a liposome cut in half. Energy in electrons, excited by light are harnessed as follows: light (cid:224) hits psii energy absorbed by pigments energy transferred to reaction center chl. a molecules electrons in these chl. a molecules excited to a higher energy state special structure of the reaction center keeps electrons from falling back to ground state. Resonance ie) only transferring energy, not electrons however, when chl. a reaction center molecules have excited electrons, these are transferred to the primary electron acceptor this leaves electron holes in the reaction center chl. a molecules electrons are replaced from water.
