What photosystem splits water?
which photosystem (p680or P700) splits water? P680
What splits water?
which photosystem (p680or P700) splits water? P680
How can plants capture light?
P680 in photosystem 2 and P700 in photosystem1, respectively.
What do the terms P680 and P700 mean in science?
i don't know this is a bad site
How many absorption peaks does chlorophyll a have?
P680 and P700 (both are red light) ;D
What special pigment do plant cells contain?
Chlorophyll in the chloroplasts and other accesory pigments (p680 in PSII and p700 in PSI)
Why are the photosystems in plants called P680 and P700?
Photosystem I is called p700 because the photosystem is 700 nanometers. It's just another name for photosystem I.
What compound is found at the reaction center of a photo system?
I believe they are chlorophyll a molecules (P680 in Photosystem II and P700 in Photosystem I) Btw, the P680 and P700 refer to wavelength size that these moecules absorb. Hope this helps.
Where do electrons get their energy from in photo system II?
PSII is a protein that is filled with chlorophyll, specifically P680. This chlorophyll captures the energy of light (light that has a wavelength of 680). That energy is used to split a water molecule into O2 and a hydrogen ion (an electron) and excites that electron that is then passed down the electron transport chain to PSI (filled with P700) where the energy in the light of the wavelength of 700 is used to excite it further.

What is the function of a thykaloid membrane?
Contain the necessary photosystems (P680, P700) and protein complexes (electron transport chain) for light-dependent reactions.
What is the difference between photosynthesis I and photosynthesis II?
Photosynthesis II or PS II (photosystem II) comes before PS I. PSII uses a pair of P680 chlorophyll a, while PSI uses a pair of P700 chlorophyll a. These systems populate the thylakoid membrane.First, light hits PS II and excites its pigment molecules and the energy bounces off the pigment molecules until it gets to the P680 chlorophyll and excites its electrons which then causes it to give off an electron to the Primary electron acceptor.Now the pair of P680 is deprived of an electron, this is where water comes nto play. An enzyme catalyzes the splitting of water to produce O2 and two electrons, these electrons supply the ones that the pair of P680 chlorophyll gave away, this enables the P680 to be able to get excited again and again without being deprived of electrons.Back to the primary acceptor, the excited electron passes from PS II to PS I via the Electron Transport chain. This produces ATP.The electron then is at the P700 pair of chlorophyll a's of PS I which excites it and it gives off that electron to another primary electron acceptor which transports its electrons via ETC as well, but the final electron acceptor is NADP+, which with the electron becomes: NADPH.
