Do the energized electrons at the primary electron acceptor flow to the reaction center?
Yes, energized electrons at the primary electron acceptor flow to the reaction center of photosystem I or II in the process of photosynthesis. This movement of electrons is essential for the conversion of light energy into chemical energy in the form of ATP and NADPH.
What does a plant do with a water?
When the light cascade finally releases the P680 electrons to the primary electron acceptor of the reaction complex those electrons must be replaced. The plant has an enzyme that preforms photolysis on water, splitting it, so that two electrons are fed one at a time into the p680 chlorophylls as replacement electrons for those they have released to the primary electron acceptor.
In chloroplasts an acceptor of electrons lost from chlorophyll and also found in the thylakoid membrane?
The acceptor of electrons lost from chlorophyll in chloroplasts is the protein complex called plastoquinone. It is an essential component of the electron transport chain in the thylakoid membrane, where it transfers electrons to other components in the chain to generate ATP and NADPH during photosynthesis.
What is the primary electron acceptor in Photosystem II?
The primary electron acceptor in Photosystem II is a molecule called plastoquinone. Plastoquinone accepts electrons from chlorophyll after they are excited by light, and transfers them to the cytochrome complex in the thylakoid membrane.
Where is the primary role of oxygen in cellular respiration chain located?
The primary role of oxygen in cellular respiration is in the electron transport chain, specifically at the end of the chain where oxygen acts as the final electron acceptor. This process generates a proton gradient that drives ATP production.
What happens after the reaction center receives energy from molecules in the light harvesting complex?
It passes the energy to the reaction center ( a specialized region of photosystem) then the energized electrons leave the reaction centers and are passed to adjacent electron transport chains (ETC)
What is the reaction that complex the part of a photosystem that donates excited electrons?
The reaction involves the transfer of excited electrons from chlorophyll to a nearby primary electron acceptor molecule. This process is vital in photosynthesis as it initiates the flow of electrons through the electron transport chain.
What is the role of oxygen in the electron transport chain of aerobic cellular respiration?
it is the final electron acceptor and then goes on to bond with two hydrogen molecules to make water or H2O The role of oxygen in cellular respiration? It removes electrons from the electron transport chain.
The electrons of which element are the primary substance carried by the electron transport system?
The electrons of hydrogen (H) are the primary substance carried by the electron transport system. In the form of hydrogen atoms or ions, electrons are shuttled through the system to generate ATP in cellular respiration.
In a protein complex for the light reaction why is energy transferred from pigment molecule to pigment molecule to a special chlorophyll a molecule and eventually to the primary electron acceptor?
Energy is transferred from pigment molecule to pigment molecule in the protein complex through resonance energy transfer, leading to excitation of a special chlorophyll a molecule called P680. This excitation of P680 causes the release of an electron, which is then transferred to the primary electron acceptor, initiating the electron transport chain in photosynthesis.
Regardless of the electron or hydrogen acceptor used one of the products of frementation is always?
Regardless of the electron or hydrogen acceptor used, one of the products of fermentation is always ATP (adenosine triphosphate). ATP is the primary energy carrier in cells and is produced during fermentation to provide energy for cellular processes.
