The electrons come from water.

In the light dependent stage water is split into hydrogen ions (H+), electrons and oxygen.

The electrons are passed on to chlorophyll, the H+ ions combine with NADP to form NADPH and the oxygen is released.

What is the source of energy that comes from the movement of electrons?

The source of energy that comes from the movement of electrons is electricity.


What is the source of electrons?

The source of electrons can be diverse, but commonly it comes from atoms through processes like ionization, where an electron is removed. In electrical circuits, electrons flow from the negative terminal of a power source (like a battery) to the positive terminal, creating an electric current.


What uses light as an energy source?

Light is a source of energy because light is energy.When photons (energy packets) of light strike certain products -- such as the silicon in solar panels, or chlorophyll in plants -- they transfer that energy by causing an electrical or electrochemical reaction.In the case of solar energy, they excite the electrons in the silicon and cause a current to flow. In plants, it triggers photosynthesis, the process of combining CO2 into sugars such as sucrose; this happens because the light photons energize the chlorophyll molecules into releasing electrons, starting the chemical process.


Why electrons of cathode does not end up after some time because of its continuous emission of electrons?

Electrons in the cathode do not end up because they are continuously being replenished by the power source connected to the cathode. This power source provides the necessary energy to liberate electrons from the cathode material, ensuring a constant supply of electrons available for emission.


When NADPH gives up its electrons?

NADPH becomes oxidized to NADP+, losing the electrons it carried. The electrons are typically used in cellular processes, such as in photosynthesis or cellular respiration, and NADP+ can then pick up more electrons to become NADPH again.

What compound is the source of electrons for linear electron flow?

In linear electron flow in the light reactions of photosynthesis, water is the source of electrons. The process involves the splitting of water molecules to release electrons, which are then used to reduce the electron carrier molecules in the electron transport chain.


Why is water important for photosynthesis and how does it contribute to the process?

Water is important for photosynthesis because it serves as a source of hydrogen atoms and electrons needed for the production of glucose. During photosynthesis, water molecules are split into oxygen, hydrogen ions, and electrons through a process called photolysis. The electrons and hydrogen ions are then used in the light-dependent reactions of photosynthesis to produce energy-rich molecules that drive the synthesis of glucose. In summary, water is essential for photosynthesis as it provides the necessary components for the production of glucose, the main product of photosynthesis.


Does mitochondria provides electrons for the cell?

No it does not. But photosynthesis provides electrons


Where do the supply of electrons come from in photosynthesis?

The supply of electrons in photosynthesis comes from water molecules. This process, known as photolysis, occurs in the light-dependent reactions of photosynthesis. Water molecules are broken down into oxygen, protons, and electrons, with the electrons being used to replenish the electrons lost in the photosystem II reaction center.


The source of energy for the process of photosynthesis?

The source of energy for the process of photosynthesis is sunlight. Through a series of complex reactions, plants and other photosynthetic organisms convert light energy into chemical energy in the form of glucose. This process is essential for the production of oxygen and is at the foundation of the Earth's food chain.


What is the source of electrons that will reduce DPIP?

The source of electrons that will reduce DPIP is usually a plant extract or isolated chloroplasts. In the process of photosynthesis, electrons are transferred from water to DPIP through the photosynthetic electron transport chain, leading to the reduction of DPIP.


Does Respiration uses sunlight as it's energy source?

No, respiration does not use sunlight as its energy source. Respiration is a process in which cells break down glucose to release energy. Sunlight is used in photosynthesis by plants to produce glucose, which is then used in respiration.


What does photosynthesis do for plant cell?

photosynthesis is the source of food for plants


What is water roles in the light reaction of photosynthesis?

Water is essential in the light reaction of photosynthesis as it serves as a source of electrons for photosystem II to replace those lost during electron transport. When water molecules are split in a process known as photolysis, oxygen is released, and electrons are transferred to chlorophyll in the photosystem, which initiates the electron transport chain.
