Question

Mention the wavelengths which show absorption maxima in the chlorophyll a molecule of reaction centres-- PS-1 and PS-2.

It's urgent plz give the answer......

Answer 1

PS-1 ->680nm
PS-2-->700nm

Answer 2

Answer:

Explanation:

1) Is the primary pigment reaction

centre in both photosystem 1 and

2 (i.e. P700 and P680) a pair of

chlorophyll a molecules?

2) If so, what is chlorophyll b? Is it

simply an accessory pigment?

Finally, if it is the case that the

primary pigment reaction centre is

chlorophyll a in both cases, how

can it be that it absorbs at a

different wavelength in the two

photosystems if it is the same

molecule?
