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 photosystem - definition?
A Photosystem is a funnel shaped cluster of photosynthetic pigments, in the thylakoid membrane of the chloroplast.
Where in the chloroplast is the chemiosmotic gradient developed?
In the thylakoid between photosystem II and photosystem I.
What protein complex absorbs in energy that used to produce NADPH?
Photosystem 1
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
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
What are the products of photosystem 2 and photosystem 1?
NADPH
What has the author Wafa M Al-Amri written?
Wafa M. Al-Amri has written: 'Investigation of the structure of photosystem 1 isolated from the chloroplast of higher plants and microalgae'
What fills the electron hole in photsystem 1 and 2?
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
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
What happen to the light energy that is trapped by the chloroplast during the first stage of photosynthesis?
Light energy is not exactly trapped. The light energy excites the electron in the reaction centres of photosystem I and photosystem II. The electron excites and transfers to the electron transport chain ( chain of electron carriers), this produces ATP. Then the electron of photosystem II is transferred by photosystem I and the electron of the photosystem I is used with H+ and NADP to form NADPH. Photosystem II gets back an electron from photolysis of water.
