What else can I help you with?
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 is a role of photosytem 2 in the light reactions?
splitting h2o
What are the two molecular groups of photosynthesis?
The two molecular groups involved in photosynthesis are chlorophyll and carotenoids. Chlorophyll is responsible for capturing light energy and initiating the light-dependent reactions, while carotenoids help protect the plant from damage by dissipating excess light energy.
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
Photosynthesis can be broken down into what?
Photosynthesis can be broken down into two main stages: light-dependent reactions and light-independent reactions (Calvin cycle). In the light-dependent reactions, light energy is used to split water molecules into oxygen, protons, and electrons. In the Calvin cycle, these electrons are used to assimilate carbon dioxide into organic molecules like glucose.
Which is a role a photosystem 2 in the light reactions?
Splitting H2o
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
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)
Which produced using the energy from photons hitting photosystem 2?
ATP and NADPH are produced using the energy from photons hitting photosystem 2 during the light-dependent reactions of photosynthesis.
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.
Photosystem 1 and photosystem 2?
Photosystem I and II are two types of reaction centers found in thylakoid membranes, which are the sites of protein synthesis located in the leaves of plants. The function of reaction centers is to convert light energy into chemical energy (photophosphorylation). Now the difference between photosystem I and photosystem II is that each is able to absorb a particular wavelength. Photosystem 2 has a maximum absorption at a wavelength of 680 nanometers. Photosystem 1 best absorbs light at a wavelength of 700 nanometers. Hope this helps!

What are the products of photosystem 1 and photosystem 2?
With the light dependent reactions the outputs (products) are oxygen, ATP, and NADPH, which carries the electrons. The oxygen is taken out and put into the environment when the NADPH (which has electrons) continues with ATP to the Calvin Cycle. Depending on how you look at it I would say that the ATP and NADPH are the most important products from the cell internally. However, we need oxygen to breathe. All three are important.
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 HAPPENS IN THE PHOTOSYSTEM 2 protein when it is hit by a photon of light?
In photosystem II, the photon of light is absorbed by a pigment molecule, which causes an electron to become excited. This electron is then passed through a series of electron carrier molecules, creating a flow of electrons used to generate ATP and NADPH during the light-dependent reactions of photosynthesis.
