Photosystem II (PSII) obtains its replacement electrons from water molecules during the process of photolysis. When water is split into oxygen, protons, and electrons, the electrons released are used to replenish those lost by PSII after it absorbs light energy. This process also generates oxygen as a byproduct, which is released into the atmosphere.
What else can I help you with?
Electrons from what replace the electrons form photosystem 2 during non cyclic electron flow?
During non-cyclic electron flow, electrons come from water molecules that are split by photosystem II. These electrons replace the ones lost by photosystem II as they are passed along the electron transport chain.
Where do electrons get there energy in photosystem 2?
Excited electrons are transferred to an electron transport chain.
How does electrons move photosytem II to photosytem?
Electrons move from Photosystem II to Photosystem I through a series of electron carrier molecules in the thylakoid membrane, known as the electron transport chain. During photosynthesis, light energy is used to transfer electrons along this chain, creating a proton gradient that drives ATP synthesis. This process is essential for the production of energy-rich molecules in the form of ATP and NADPH.
What step occur in photosystem 2?
In Photosystem II, the process begins when light energy is absorbed by chlorophyll, exciting electrons and initiating the electron transport chain. Water molecules are split in a process called photolysis, releasing oxygen and providing replacement electrons for the chlorophyll. The energized electrons are then transferred through a series of proteins in the thylakoid membrane, ultimately contributing to the production of ATP and NADPH. This process is crucial for capturing and converting solar energy into chemical energy in plants.
What Photosystem is older in terms of evolutionary history?
Photosystem II is older in terms of evolutionary history compared to Photosystem I. Photosystem II is thought to have evolved before Photosystem I as it evolved to oxidize water in order to provide electrons for the electron transport chain, which Photosystem I then uses to reduce NADP+ to NADPH.
Electrons from what replace the electrons from photosystem 2 during noncyclic electron flow?
water
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.
Electrons form replace the electrons from photosystem 2 during noncyclic electric flow?
water
Electrons from what replace the electrons form photosystem 2 during non cyclic electron flow?
During non-cyclic electron flow, electrons come from water molecules that are split by photosystem II. These electrons replace the ones lost by photosystem II as they are passed along the 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.
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.
Where do electrons get there energy in photosystem 2?
Excited electrons are transferred to an electron transport chain.
How does water participate in the light reactions of photosynthesis?
