PSYC 2000 Lecture Notes - Lecture 24: Thylakoid, Atp Synthase, Large Hadron Collider
Document Summary
Energy in proteins used to pump protons across membranes (actively transport) Requires energy and moves from low to high concentration. Energy comes from movement of excited electron. Concentration gradient larger inside of thylakoid bc of the protons being pumped in. Protons will want to move from high to low but cannot on their own bc they can"t get thru membrane - need facilitated diffusion. A protein forms in membrane that allows protons to move across. This membrane grabs onto adp and phosphate. When the protons go thru this membrane, it gives the energy to the protein so that it can make atp. Chemiosmosis - in thylakoid membrane = photo part of photosynthesis. Ps ii responsible for controlling concentration gradient w protons. Atp generation in chloroplasts, mitochondria, and prokarya (bacteria and archaea) all eukaryotes have mitochondria. 1) as excited electrons are passed down the ets, protons are pumped across a membrane to form concentration gradient (drew on board)
