Question

Difference between PS1 and PS2.​

Answer 1

ANSWER

1️⃣The main difference between the two is the wavelengths of light to which they respond.

Photosystem1 absorbs light with wavelengths shorter than 700nm,whereas photosystem2 absorbs light with wavelengths shorter than 680nm.However, they are both equally important question in the process of oxygenic photosynthesis.

2️⃣ Photosystem1

Photosystem1 contains the chlorophyll-A molecule P700,which absorbs wavelengths shorter than 700nm.It receives energy from photons, in addition to the associated accessory pigments in its antenna system, and from the electron transport chain from photosystem2.It uses the energy from light to reduce NADP+(nicotinamide adenine dinucleotide phosphate) to NADPH+ H+, or simply to power a photon pump(plastoquinone or PQ).

Photosystem2

It is the first protein complex in the light-dependent photosynthesis, contains the chlorophyll-A molecule P680 that absorbs light with wavelengths shorter than 680nm. It receives energy from photons & from associated accessory pigments in it's antenna system & uses it to oxidize water molecules, producing protons(H+) & O2 as well as passing an electron to the electron transport chain.
