What molecule absorbs sunlight in photosynthesis?
Photosystem II
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.
How do electrons gain in energy in photosystem 1?
they absorb photons from sunlight
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.
Which is a reactant in the process powered by sunlight hitting photosystem 11?
In the process powered by sunlight hitting Photosystem II, water (H₂O) is a key reactant. When light energy is absorbed by Photosystem II, it leads to the splitting of water molecules through a process known as photolysis. This reaction generates oxygen (O₂) as a byproduct and provides electrons that are essential for the photosynthetic electron transport chain.
Which sentence best describes what happens after sunlight hits photo system 2?
After sunlight hits photosystem 2, it excites electrons within photosystem 2. These electrons are then passed down an electron transport chain to photosystem 1, where they help generate ATP through a series of redox reactions.
Which sentence best describes what happen after sunlight hits photosystemll?
After sunlight hits photosystem II, it energizes electrons that are passed through the electron transport chain to photosystem I. This process helps establish a proton gradient across the thylakoid membrane and powers ATP production through ATP synthase. The energized electrons eventually combine with NADP+ to form NADPH, which is used in the Calvin cycle to produce sugars.
What molecule absorbs sunlight in photosynthesis?
Photosystem II
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.
If the number of hydrogen ions being pumped into the thylakoid is rapidly decreasing what is most likely happening?
Less sunlight is being used by photosystem II
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 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.
How do electrons gain in energy in photosystem 1?
they absorb photons from sunlight
Where do electrons get their energy in photosystem II?
From energy in photons
The molecule responsible for first capturing the photons energy from sunlight is?
They are the chlorophyll. Photosystem II reacts first
What will be the result photosystem 2 being exposed to less sunlight?
Fewer hydrogen ions will be pumped into the thylakoid
How can you use nocturnal in a sentence?
Bats can be nocturnal since they depend more on ecolocation than on sunlight. Nocturnal describes something that is awake during the night. Diurnal describes something that is awake during the day.
