Within the photosystem, enzymes capture photons of light to energize electrons that are then transferred through a variety of coenzymes and cofactors to reduce plastoquinone to plastoquinol. The energized electrons are replaced by oxidizing water to form hydrogen ions and molecular oxygen. By What is the function of a photon in the photosystem 2. It comes down from an energy source and hit photosystem 2 and is absorbed by the light harvesting complexes. What is the function of light harvesting complexes. Bounce the proton between each complex until it eventually reaches the P680. What does H20 give to P680.
For each of the steps below, identify what starts the reaction, what is created, and where it takes place. a. Light Dependent Reactions - chloroplast and within the thylakoid membrane.
Explain photosystem 1 and photosystem 2. Light reactions photosystem diagram central air conditioner wiring diagram 2004 pontiac sunfire radio wiring diagram. Photosystem ii or water plastoquinone oxidoreductase is the first protein complex in the light dependent reactions of oxygenic photosynthesis. The diagram does not show where and how atp is made.
It comes down from an energy source and hit photosystem 2 and is absorbed by the light harvesting complexes. What is the function of light … This diagram showcases the enzymes and steps of photosystem i and photosystem ii and explores how these systems create a concentration gradient which powers the production of atp through the atp synthase compound.
The photosynthetic water-splitting mechanism is catalyzed by a water:plastoquinone oxido-reductase by the name of photosystem II (PSII), which
