Best Answer

Photosystem I and II are two types of reaction centers found in thylakoid membranes, which are the sites of protein synthesis located in the leaves of plants.

The function of reaction centers is to convert light energy into chemical energy (photophosphorylation).

Now the difference between photosystem I and photosystem II is that each is able to absorb a particular wavelength.

Photosystem 2 has a maximum absorption at a wavelength of 680 nanometers.

Photosystem 1 best absorbs light at a wavelength of 700 nanometers.

Hope this helps!

They are called photosystem one and two (PSI and PSII). Oddly PSII comes before PSI (it was discovered first). Both photosystems are employed by photosynthesis which excite photons and convert the energy. This energy gets sent to the Calvin cycle where Pyruvate (a half sugar) is produced. The plants store this sugar as a food source.

To be brief, photosynthesis is separated into two parts: the light reactions (photosystem 2 and 1) and the dark reactions (the Calvin cycle). The photosystems produce NADP+ which are powerful electron acceptors and ATP. Both of which power the Calvin cycle. The photosystems absorb water and release oxygen. The chief difference between photosystem 2 and 1 is that they absorb different wavelengths of light more effectively.

Which photosystem is used first in photosynthesis?

Photosystem 2 happens in photosynthesis before photosystem 1. However they are numbered in order of how they were discovered. Photosystem 1 was discovered before photosystem 2. In photosynthesis the order of them is 2 then 1. meaning that photosystem 1 was discovered 1st but photosystem 2 happens 1st in photosynthesis


Where does photosystem 2 and photosystem 1 occur?

1. Photosystem I is found in the membrane facing the inside of the grana and Photosystem II is found in membrane facing the stromaTHYLAKOID MEMBRANE


What are the products of photosystem 2 and photosystem 1?

NADPH


What fills the electron hole in photsystem 1 and 2?

In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2


What protein complex absorbs in energy that used to produce NADPH?

Photosystem 1


How does electrons move photosytem II to photosytem?

No, they move from photosystem 2 to photosystem 1. 2 evolved first but was not discovered until after photosystem 1.


What are the two molecular groups of photosynthesis?

Photosystem 1 and Photosystem 2


Is photosystem 2 light dependent?

Both photosystem 2 & 1 are light-dependent.


What is the explanation for the pathway of electron transport chain?

It's a pathway where electrons are transported from photosystem 2 to photosystem 1.


Where does photosystem 2 and photosystem 1 take placein the organelle?

Photosystems I and II are both in the thylakoid membranes of the chloroplast.


What is a role of photosystem 2 in light reactions?

Photosystem two produces O2, ATP, and NADP+


What happens to electrons when pigments in photosystem absorb lights?

Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water. For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.
