Photosynthesis can be broken down into what?
(1) Light-dependent reactions which is where photosystem 2 and 1 and the ETC take place. (2) Light-independent reactions which is where the Calvin cycle take place.
Is photosystem 2 light dependent?
Both photosystem 2 & 1 are light-dependent.
What is a role of photosytem 2 in the light reactions?
splitting h2o
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 fills the electron hole in photsystem 1 and 2?
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
Which is a role a photosystem 2 in the light reactions?
Splitting H2o
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)

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.
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!
Are ATP molecules made during the light-independent reactions of photosynthesis?
An electron transport chain is gone through when electrons are transferred from photosystem 1 to photosystem 2. ETC pumps protons through the thykaloid. Protons are diffused out of the thykaloid and through the ATP synthase.
How can plants capture light?
P680 in photosystem 2 and P700 in photosystem1, respectively.
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.
