PSYC 2000 Lecture Notes - Lecture 22: Light-Harvesting Complex, Photosynthetic Reaction Centre, Large Hadron Collider
Document Summary
Nucleus = 1 proton, no neutrons, 1 electron. Overall zero charge (equal # of positively charged protons and negatively charged electrons. E- leaves, becomes positively charged - cation, or hydrogen ion. Leaves - millions of cells w several chloroplasts in ea cell. Green blobs inside membrane of thylakoids = chlorophylls. Absorbs everything but green and a little bit of yellow. Blue blobs - proteins that consists of sequences of aa. Create wires of proteins in which electrons move. Photons that are harvested produce wired electrons. Special chlorophyll called reaction center that shoots electrons thru wire. Electrons move from chlorophylls to proteins that pass the hot potato or electron from left to right. Once the last protein gets the electron, they go to the next set of chlorophyll and proteins. Electrons excited, energy transferred when electrons passed to other proteins. These proteins w this energy and movement of electrons make atp. Work backwards - bc pt ii was discovered first.
