In Photosystem II, the process begins when light energy is absorbed by chlorophyll, exciting electrons and initiating the electron transport chain. Water molecules are split in a process called photolysis, releasing oxygen and providing replacement electrons for the chlorophyll. The energized electrons are then transferred through a series of proteins in the thylakoid membrane, ultimately contributing to the production of ATP and NADPH. This process is crucial for capturing and converting solar energy into chemical energy in plants.
What else can I help you with?
What fills the electron hole in photsystem 1 and 2?
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
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 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+
Is photosystem 2 light dependent?
Yes, photosystem 2 is a light-dependent process in photosynthesis. It absorbs photons to initiate the light-dependent reactions of photosynthesis, where it helps generate oxygen and produce ATP and 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.
Which steps occur in photosystem II?
ADP takes on energy and a phosphate to produce ATP in photosystem II.
What fills the electron hole in photsystem 1 and 2?
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
What are the products of photosystem 2 and photosystem 1?
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
How do photosystem 1 and 2 allow the calvin cycle to work?
No. Photosystems I and II are where light-dependent reactions occur, while the Calvin Cycle is where light-independent reactions occur. Photosynthesis begins with Photosystem II, then Photosystem I, then the products from there go to the Calvin Cycle. (yes photosystem II comes before photosystem I)
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+
Is photosystem 2 light dependent?
Yes, photosystem 2 is a light-dependent process in photosynthesis. It absorbs photons to initiate the light-dependent reactions of photosynthesis, where it helps generate oxygen and produce ATP and NADPH.
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 sentence best describes what happens after sunlight hits photo system 2?
After sunlight hits photosystem 2, it excites electrons within photosystem 2. These electrons are then passed down an electron transport chain to photosystem 1, where they help generate ATP through a series of redox reactions.
Which is a role a photosystem 2 in the light reactions?
Splitting H2o
