In photosystem I (PSI), the primary event is the absorption of light energy by chlorophyll pigments, which excites electrons to a higher energy state. These high-energy electrons are then transferred through a series of proteins in the electron transport chain, ultimately reducing NADP+ to form NADPH. This process is crucial for the light-dependent reactions of photosynthesis, providing the reducing power needed for the Calvin cycle. Additionally, PSI plays a role in cyclic electron flow, which helps generate ATP.
What else can I help you with?
What occurs to water molecules as a result of the actions of photosystem II?
They are split into oxygen and hydrogen.
What is cooperation of the two photosystems of the chloroplast is required for?
The cooperation of the two photosystems (Photosystem I and Photosystem II) is required for the efficient production of ATP and NADPH during the light-dependent reactions of photosynthesis. Photosystem II generates ATP through the electron transport chain, while Photosystem I produces NADPH. Working together, they create the energy carriers needed to fuel the Calvin cycle, where carbon fixation occurs.
Is carbon dioxide a photosystem II outputs?
No, carbon dioxide is not a direct output of Photosystem II in photosynthesis. Photosystem II's primary function is to harvest light energy and use it to split water molecules into oxygen, protons, and electrons. Carbon dioxide is utilized in the Calvin cycle, which occurs in a different part of the chloroplast.
Photosynthetic unit where solar energy is absorbed and high energy electrons are generated?
The photosynthetic unit where this occurs is the photosystem. Photosystems I and II are responsible for absorbing solar energy and generating high-energy electrons through the process of photosynthesis. These electrons are then used to power the production of ATP and NADPH, key molecules for further energy conversion in the plant cell.
What fills the electron hole in photsystem 1 and 2?
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
What occurs to water molecules as a result of the actions of photosystem II?
They are split into oxygen and hydrogen.
The what of an event is how many times it occurs?
Probability of an event is how many times it occurs.
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.
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 carbon dioxide a photosystem II outputs?
No, carbon dioxide is not a direct output of Photosystem II in photosynthesis. Photosystem II's primary function is to harvest light energy and use it to split water molecules into oxygen, protons, and electrons. Carbon dioxide is utilized in the Calvin cycle, which occurs in a different part of the chloroplast.

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.

What happens to electrons when pigments in photosystem absorb lights?
Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water. For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.
What is an event that occurs every year called?
Annual event
What fills the electron hole in photsystem 1 and 2?
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
