The role of photosystem II is to capture sunlight and initiate the process of photosynthesis by using light energy to split water molecules into oxygen, protons, and electrons. This process replenishes electrons in the photosynthetic electron transport chain and ultimately leads to the generation of ATP and NADPH for the Calvin cycle.
What else can I help you with?
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 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.
What happens when a photon of light hits photosystem 2?
When a photon of light hits photosystem 2, it excites an electron within the reaction center of the photosystem. This electron is then transferred along an electron transport chain, resulting in the generation of ATP and the splitting of water molecules to release oxygen as a byproduct.
What Is a role in photosystem 1?
In photosystem 1, the role of the reaction center chlorophyll is to absorb photons and initiate the electron transport chain. It passes excited electrons to an electron acceptor, which then moves them through a series of electron carriers to produce NADPH. This process is essential for the conversion of light energy into chemical energy during photosynthesis.
The energy from photons hitting photosystem 2 is used to produce what?
ATP
Which is a role a photosystem 2 in the light reactions?
Splitting H2o
What is a role of photosystem 2 in light reactions?
Photosystem two produces O2, ATP, and NADP+
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
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 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
Which role is of photosystem ii in the light reactions?
Splitting H2O (Apex)
Which is a role of photosystem ii in the light reaction?
Splitting H2O (Apex)
Where does photosystem 2 and photosystem 1 take placein the organelle?
Photosystems I and II are both in the thylakoid membranes of the chloroplast.
Which is the role of a photosystem I in the light reactions?
To make energy-carrier molecules like NADPH
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.
Which is role of photosystem in the light reactions?
to make energy-carrier molecules like NADPH Apex
