Sunlight excites electrons in the chlorophyll during the what?
Sunlight excites electrons in chlorophyll during the process of photosynthesis, where they are used to convert carbon dioxide and water into glucose and oxygen. This excitation of electrons is a key step in converting light energy into chemical energy that the plant can use for growth and metabolism.
Where does the energy come from that excites the electrons in chlorophyll?
The energy that excites electrons in chlorophyll comes from sunlight. Specifically, chlorophyll absorbs light energy from the sun, which is then used to power the process of photosynthesis.
What is the unit of hundreds of chlorophyll molecules that trap the energy of sunlight?
The unit of hundreds of chlorophyll molecules that trap the energy of sunlight is typically referred to as a "photosystem." In plants, these photosystems, primarily Photosystem I and Photosystem II, contain clusters of chlorophyll molecules that work together to capture light energy during photosynthesis.
What happens to the electrons when sunlight hits the leaves?
When sunlight hits the leaves, the energy from the light is absorbed by chlorophyll, the green pigment in the chloroplasts. This absorbed energy excites electrons in the chlorophyll molecules, raising them to a higher energy state. These high-energy electrons are then transferred through a series of proteins in the thylakoid membrane, initiating the process of photosynthesis, which ultimately converts light energy into chemical energy stored in glucose.
What electrons excited by sunlight in Photosystem are replaced with?
In Photosystem II, electrons excited by sunlight are replaced by electrons derived from the splitting of water molecules (photolysis). This process releases oxygen as a byproduct and provides the necessary electrons to replenish those lost by the chlorophyll when it absorbs light energy. In Photosystem I, the excited electrons are eventually transferred to NADP+, forming NADPH, which is crucial for the Calvin cycle in photosynthesis.
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.
What happens after sunlight hits photo system two?
After sunlight hits Photosystem II, it energizes the electrons in the chlorophyll molecules. The energized electrons are then passed through an electron transport chain, generating ATP and NADPH molecules through the process of photophosphorylation.
When sunlight excited electrons in chlorophyll how do the electrons change?
the electrons gain a huge amount of energy
What is the effect of sunlight on plants?
At first, sunlight causes an increase in photosynthesis. At some point, photosynthesis stops increasing with increasing sunlight. At this point, the chlorophyll molecules are saturated. Further increases in sunlight cause a decrease in photosynthesis as chlorophyll molecules are destroyed.
Which is a reactant in the process powered by sunlight hitting photosystem 2?
The reactant in the process powered by sunlight hitting photosystem 2 is water. In this process, water is split into oxygen, protons, and electrons when sunlight is absorbed by chlorophyll molecules.
Where do electrons get their energy in photosystem II?
From energy in photons

This excitation of electrons is a key step in converting light energy into chemical energy that the plant can use for growth and metabolism.
When sunlight excites electrons in chlorophyll how do electrons change?
As red and blue light energy is absorbed by Chlorophyll electrons in outer shell are excited & raised to a higher energy level.
