There are two types of cytochrome b, one in the chloroplasts and one in the mitochondria.
The complex is supposed to absorb light.
The diagram shows the variation in the energy of an electron.
The energy may be transferred from the multiple to the single.
The P680 is named after it's ability to light energy and produce various chemicals.
You have learned that you can absorb light at a wavelength of 680 nm.
In either case, when capture that energy in the form of excited electrons, they absorb light energy and phyll pigment in the light-harvesting complexample.
The molecule is designated P680, because an electron in it is excited.
The water oxidizes.
A light-harvesting complex tron in a pigment molecule is very unstable.
A reaction center is1-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-6556
The transfer of the electron from P680 to the pri mary electron acceptor is very fast.
The primary electron has a lot of time to release its energy.
Light can be used to perform cellular work.
Let's have an energy level.
The electron that has been removed must be replaced in order to function again.
When P680 becomes P680+, it's removed.
Oxygen gas is formed by the oxidation of water, which is used by many organisms for cellular respiration.
Explain the roles of the light- electron acceptor harvesting complex, P680, and the primary electron during the absorption of light energy by where it is very photosystem II.
P680 becomes P680+.
The absorption of light is the topic of P680.
Light absorption begins at the light 2 H+ + 1/2 O2 harvesting complex, which converts light into energy.
Compare form when an excited electron is transferred to the light-harvesting complex and the role of the primary electron acceptor.
