What else can I help you with?
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 groups of molecule are involved in photosynthesis?
Photosystem
What molecule absorbs sunlight in photosynthesis?
Photosystem II
What sequence accurately reflects the flow of electrons in photosynthesis?
In photosynthesis, electrons flow from water molecules to photosystem II, then to photosystem I, and finally to NADP+ ultimately producing NADPH. Along the way, the electrons generate a proton gradient that drives ATP production.
What is the start of photosynthesis?
pigments in photosystem II absorb light
Is photosynthesis a system?
Photosynthesis is not a system. It is a process in plants. It is very important process.Photosynthesis is a process of making sugars from CO2 and water by using light energy. Photosystem I and photosystem II are involved in this process to transfer electrons across the membrane. Photosynthesis occurs in plants algae and certain bacteria.
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.
How does water participate in the light reactions of photosynthesis?
Donating electrons to photosystem 2
What is true about the light reaction?
photosynthesis begins when pigments in photosystem i absorb light.
What is the difference between photosystem one and two?
Photosystem I absorbs light best at a wavelength of 700 nm, while Photosystem II absorbs light best at a wavelength of 680 nm. Photosystem I transfers electrons to reduce NADP+ to NADPH, while Photosystem II replenishes electrons lost in the process of photosynthesis. Both photosystems work together in the light-dependent reactions of photosynthesis to ultimately produce ATP and NADPH.
What is a photosystem made up of and where is it located?
A photosystem is a complex of proteins and pigments, primarily chlorophyll, that facilitates the capture of light energy during photosynthesis. There are two types of photosystems: Photosystem I (PSI) and Photosystem II (PSII), both of which are located in the thylakoid membranes of chloroplasts in plant cells. These structures play a crucial role in converting light energy into chemical energy, driving the process of photosynthesis.
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.
