Photosynthesis Light Dependent Reactions
| Question | Answer |
|---|---|
| photosynthetic pigments are located on the thylakoid membrane are organized into clusters with proteins called.... | photosystems |
| proteins + 200-300 pigment molecules = | photosystem |
| each photosystem is located on the membrane next to an ____ ("functional partners") | ETC- electron transfer chain |
| specific kinds of enzymes, co-enzymes or other proteins that are organized to accept and give up electrons, one after the other at a cell membrane between two compartments is called a... | Electron Transfer Chain |
| the electrons are at a ____ energy level when they enter the ETC than when they leave; "lose/gain" energy along the way and make____ | higher, lose, ATP |
| in light ____ reactions photosynthetic pigments absorb photons of appropriate wavelength | dependent |
| in light dependent reactions electrons in the pigment are boosted to a higher energy level, then return to their ground state, releasing energy which is passed to a chlorophyll a molecule in the "____" | reaction center |
| the cyclic pathway of ATP formation uses... | PS 1 (Photosystem 1) |
| as photosynthetic organisms evolved, cyclic flow did not provide enough... | energy |
| ____ evolved, work in tandem with PS1, provides enough energy to split water to get electrons... | type II photosystems |
| non-cyclic electron flow uses... | PS II (Photosystem 2) |
