What does light do when it strikes the chlorophyll molecules of photosystems?
When light strikes the chlorophyll molecules of photosystems, it excites electrons within the chlorophyll, raising them to a higher energy state. This energy is then used to initiate the process of photosynthesis, facilitating the conversion of light energy into chemical energy. The excited electrons are transferred through a series of proteins in the thylakoid membrane, ultimately leading to the production of ATP and NADPH, which are essential for the energy requirements of the plant.
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.
Do leaves in plant has highest water potential?
No, leaves in plants do not have the highest water potential. Water potential is typically highest in the roots, where water is absorbed from the soil. As water moves through the plant, it loses potential due to factors like transpiration and solute concentration, resulting in lower water potential in the leaves. Therefore, the highest water potential is generally found in the soil and roots, while the leaves usually have a lower water potential due to the loss of water during transpiration.
How does it eletricity flow?
Electricity flows through a circuit due to the movement of electrons in a conductor, such as a wire. This movement is driven by an electric potential difference, or voltage, that causes the electrons to flow from areas of higher potential to areas of lower potential. The flow of electricity forms a complete loop through the circuit, allowing for the transfer of energy to power devices.
What are the products of the light reaction and how they formed?
The products of the light reaction are ATP, NADPH, and oxygen. These molecules are formed through the process of photophosphorylation in the thylakoid membrane of chloroplasts. Water is split into oxygen, protons, and electrons, providing the electrons needed to generate ATP and NADPH.
What electron move high energy between photosystems?
The electrons that move between photosystems in photosynthesis are energized by sunlight and carried by electron carrier molecules such as plastocyanin and ferredoxin. These high-energy electrons are transferred through a series of redox reactions in the electron transport chain to generate ATP and NADPH for the light-dependent reactions of photosynthesis.
What is the force that causes electrons to flow through a conductor known as?
The force that causes electrons to flow through a conductor is known as voltage or electromotive force (EMF). Voltage provides the "push" or potential difference that drives electrons from areas of higher potential to lower potential, resulting in an electric current.
What do you call Electricity is the movement of what through a conductor?
Electricity is the movement of electrons through a conductor. Electrons are negatively charged particles that flow from a higher potential to a lower potential, creating an electric current.
For electrons to flow continuously through a conductor there must be a?
closed electrical circuit that provides a path for the electrons to flow from a high potential to a low potential.
What creates an electric force field that moves electrons through a circuit?
An electric potential difference, also known as voltage, creates an electric force field that moves electrons through a circuit. Electrons flow from areas of high potential (voltage) to areas of low potential, creating an electric current in the circuit.
What is the flow of electrons through material?
The flow of electrons through a material is the movement of negatively charged electrons from an area of higher electric potential to an area of lower electric potential. This movement creates an electric current that can be harnessed for various applications, such as generating electricity in a conductor. The flow of electrons is driven by an electric field that exists due to a potential difference between two points in the material.
What driving force which causes electrons to flow through conductors is called?
The driving force that causes electrons to flow through conductors is called voltage. Voltage creates an electric field that pushes the electrons in a circuit, enabling them to move from higher potential to lower potential.
What is needed to get electrons flowing through a wire?
A driving Force i.e A difference in the potential.
When water molecules are split in plants where do the electrons and hydrogens ions go?
Electrons are used to replenish the electrons lost by the photosystems (electrons in photosystems are lost to the electron transport chain and eventually end up in NADPH). The protons are used by the proton pumps in the electron transport chain to create the proton gradient, which drives ATP synthesis.
How is kinetic and potential energy involved when electrons move through a closed path?
When electrons move through a closed path, they possess kinetic energy due to their motion. As they move against an electric field, they also have potential energy, which is converted into kinetic energy as they move. This interplay between kinetic and potential energy is essential for the flow of electrons in a closed circuit.
What does a current flow of electrons need?
Your question is not clear. A current is generated when a group of electrons flow through a conductor, and this happens when there is a potential difference between the 2 ends of the conductor. If you want to know how can we start the flow of electrons it is by creating a potential difference in between the 2 ends of the conductor.
Is voltage the flow of electrons through a wire or a conductor?
The flow of electrons through a conductor is called electric current.The voltage is the 'pressure' or difference in electric potential between theends of the wire, that encourages each electron to try to move closer toone end and farther away from the other end.
