Water participates directly in the light reactions of photosynthesis by?
Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II during the process of photolysis. These electrons are used to replace the ones lost by chlorophyll when it absorbs light energy, allowing the photosystem to continue absorbing light and generating ATP and NADPH for the Calvin cycle.
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.
Where do electrons get their energy in photosynthesis l?
In photosynthesis, electrons gain their energy from sunlight, which is absorbed by chlorophyll and other pigments in plant cells. This energy excites the electrons, raising them to a higher energy state. The energized electrons then move through the electron transport chain, facilitating the conversion of light energy into chemical energy, ultimately leading to the production of glucose and oxygen.
During photosynthesis what causes electrons to flow from water to NADP plus?
During photosynthesis, light energy is absorbed by chlorophyll in the thylakoid membrane of the chloroplast. This energy excites electrons in Photosystem II, causing them to flow down an electron transport chain that eventually leads to the reduction of NADP+ to NADPH, along with the generation of ATP.
Why would most what is a reactant in the process powered by sunlight hitting photosynthesis II?
In photosynthesis, particularly in Photosystem II, the primary reactant powered by sunlight is water (H₂O). When sunlight is absorbed by chlorophyll, it excites electrons, leading to the splitting of water molecules in a process known as photolysis. This reaction produces oxygen (O₂), protons (H⁺), and electrons, which are essential for the subsequent stages of photosynthesis. Thus, water serves as a crucial reactant that initiates the conversion of solar energy into chemical energy.
Where do electrons get there energy from photostem 2?
Electrons in photosystem II get their energy from sunlight. When photons from sunlight are absorbed by the chlorophyll molecules in the photosystem, the energy is transferred to electrons, allowing them to become excited and drive the process of photosynthesis.

These electrons are used to replace the ones lost by chlorophyll when it absorbs light energy, allowing the photosystem to continue absorbing light and generating ATP and NADPH for the Calvin cycle.
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.

What is the photosynthetic pigment that is essential for photosynthesis to occur?
This pigment is chlorophyll. It is struck by photons of light which excites it's electrons into a higher energy level where they enter photosystem II.
Where do electrons get their energy in photosystem II?
From energy in photons

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.
What is produced when using the energy from photons hitting photsystem II?
When photons hit photosystem II in the thylakoid membrane of chloroplasts, they excite electrons that are used to split water molecules into oxygen, protons, and electrons. The oxygen is released as a byproduct, while the electrons are used to generate ATP and NADPH through the process of photosynthesis.
What sequence accurately reflects the flow of electrons in photosynthesis?
In photosynthesis, electrons flow from water molecules to photosystem II, then to photosystem I, and finally to NADP+ ultimately producing NADPH. Along the way, the electrons generate a proton gradient that drives ATP production.
