What else can I help you with?
An electron transport chain connects photosystem1 and photosystem2?
They return to Photosystem I
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 protein complex absorbs in energy that used to produce NADPH?
Photosystem 1
After electrons leave photosystem II they go into an electron transport chain of three protein complexes Where do they go after that electron transport chain?
They go into photosystem I.
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.
Water participates directly in the light reactions of photosynthesis by?
Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II during the process of photolysis. These electrons are used to replace the ones lost by chlorophyll when it absorbs light energy, allowing the photosystem to continue absorbing light and generating ATP and NADPH for the Calvin cycle.
How does water participates directly in the light reactions of photosynthesis?
donating electrons to photosystem II
An electron transport chain connects photosystem1 and photosystem2?
They return to Photosystem I
True or false an electron transport chain connects photosystem 1 and photosystem2?
False. The electron transport chain connects the two photosystems in the thylakoid membrane, but it does not directly connect photosystem 1 and photosystem 2. Instead, it shuttles electrons between the two photosystems as part of the light-dependent reactions of photosynthesis.
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.
How do the reaction centers of photosystem you and II differ?
Photosystem 1 has chlorophyll a molecule which absorbs maximum light of 700 nm and is called P700 whereas photosystem 2 has chlorophyll a molecule which absorbs light of 680 nm and is called P680.
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.
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 reactants and products of photosystem 1?
In Photosystem I (PSI), the primary reactants are light energy, water, and electrons, which are derived from the electron transport chain of Photosystem II. The main products of PSI are NADPH, a reduced electron carrier, and ATP, generated through the associated electron transport processes. The light energy absorbed by PSI drives the transfer of electrons, ultimately leading to the reduction of NADP+ to NADPH.
