Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The reaction-center chlorophyll of photosystem is known as P700 because
A
there are 700 chlorophyll molecules in the center
B
the pigment best at absorbing light with a wavelength of 700 nm
C
there are 700 photosystem I components to each chloroplast
D
it absorbs 700 photons per microsecond
Explanation: 

Detailed explanation-1: -This question is about the meaning of abbreviation p. We know that P 700 is derived from the world pigment And the ability to absorb, based at 700 nm. So the reaction center chlorophyll of photo system one is known as P 700 because, and the answer will be option. This pigment mhm, is best at absorbing light.

Detailed explanation-2: -The reaction-center chlorophyll of photosystem I is known as P700 because. there are 700 chlorophyll molecules in the center.

Detailed explanation-3: -This species is vital due to its ability to absorb light energy with a wavelength approximately between 430 nm-700 nm, and transfer high-energy electrons to a series of acceptors that are situated near it.

Detailed explanation-4: -In PS I the reaction centre chlorophyll a has an absorption peak at 700 nm, hence is called P700, while in PS II it has absorption maxima at 680 nm, and is called P680.

Detailed explanation-5: -The chlorophyll a special pairs of the two photosystems absorb different wavelengths of light. The PSII special pair absorbs best at 680 nm, while the PSI special absorbs best at 700 nm.
