What else can I help you with?
How many times are electrons energized during photosynthesis?
The thylakoid membrane contains 2 photosytems, known as Photosystem I and Photosystem II. Together, they function to absorb light and transfer energy to electrons.
What are the products of photosystem 2 and photosystem 1?
NADPH
Where does photosystem 2 and photosystem 1 occur?
Photosystem 2 is located in the thylakoid membrane of the chloroplasts, while Photosystem 1 is located downstream from Photosystem 2 in the thylakoid membrane. Both photosystems are important for light-dependent reactions during photosynthesis.
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.
What fills the electron hole in photsystem 1 and 2?
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
What Photosystem is older in terms of evolutionary history?
Photosystem II is older in terms of evolutionary history compared to Photosystem I. Photosystem II is thought to have evolved before Photosystem I as it evolved to oxidize water in order to provide electrons for the electron transport chain, which Photosystem I then uses to reduce NADP+ to NADPH.
Some photosynthetic organisms contain chloroplasts that lack photosystem II yet are able to survive so what is the best way to detect the lack of photosystem II in these organisms would be?
One way to detect the lack of photosystem II in photosynthetic organisms is to measure the rate of oxygen production during photosynthesis. Photosystem II is responsible for splitting water molecules and releasing oxygen as a byproduct, so the absence of photosystem II would result in reduced or no oxygen production. Another method is to analyze the pigment composition of the chloroplasts since photosystem II contains specific pigments like chlorophyll a and beta-carotene. If these pigments are absent or reduced, it can indicate the lack of photosystem II.
What is contained in each photosynthetic unit of photosystem 1?
Photosystem I contains photosynthetic units with :- 200 or more molecules of chlorophyll a,- small amounts of chlorophyll b- protein saddled carotenoid pigment,-a pair of specialized reaction-center molecules of chlorophyll called P700
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 protein complex absorbs in energy that used to produce NADPH?
Photosystem 1
Which photosystem most likely envolved first?
Photosystem II most likely evolved first because it provides the energy for producing ATP and passes its electrons to photosystem I.
What is a photosystem - definition?
A Photosystem is a funnel shaped cluster of photosynthetic pigments, in the thylakoid membrane of the chloroplast.
