What else can I help you with?
What molecule precedes the electron transport chain of both photo-system you and photo- system II?
The molecule that precedes the electron transport chain in both photosystem I and photosystem II is plastoquinone. Plastoquinone accepts electrons from the reaction center chlorophyll in both photosystems and transfers them to the cytochrome b6f complex to ultimately generate ATP.
Which complex in the electron transport chain transfers electrons to the final electron acceptor?
The complex in the electron transport chain that transfers electrons to the final electron acceptor is called Complex IV, also known as cytochrome c oxidase.
What are the names of the complexes involved in the electron transport chain?
The complexes involved in the electron transport chain are named Complex I, Complex II, Complex III, Complex IV, and Complex V (also known as ATP synthase).
What protein complex absorbs in energy that used to produce NADPH?
Photosystem 1
Which of the following statements regarding events in the functioning of photosystem II is false?
Statement: "The splitting of water molecules in the oxygen-evolving complex results in the release of oxygen gas." This statement is false. The splitting of water molecules in the oxygen-evolving complex results in the release of protons and electrons, not oxygen gas.
What is composed of a light-harvesting complex and an electron transport system?
A photosystem is composed of a light-harvesting complex and an electron transport system. The light-harvesting complex captures light energy and transfers it to the reaction center, where electrons are excited and transferred through the electron transport system to generate ATP and NADPH during photosynthesis.
What molecule precedes the electron transport chain of both photo-system you and photo- system II?
The molecule that precedes the electron transport chain in both photosystem I and photosystem II is plastoquinone. Plastoquinone accepts electrons from the reaction center chlorophyll in both photosystems and transfers them to the cytochrome b6f complex to ultimately generate ATP.
What is Electron Transport Systems?
The electron transport system is a series of protein complexes and molecules in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors, generating ATP in the process. This process is crucial for cellular respiration and energy production in aerobic organisms.
Is the energy from sunlight trapped by chlorophyll located in the electron transport chain?
No, the energy trapped by chlorophyll is located in photosystem I and II. Light energy is first captured by PS II and an electron is then transferred to a primary electron acceptor known as plastoquinone. Pq then transfers it's electron to the cytochrome complex that transfers its energy to the electron transport system which passes it on to plastocyanin which in turn gives its electron to PS I where it is re-excited by photons. This process is known as the electron transport but the energy captured by chlorophyll is located in the photosystems.
Which complex in the electron transport chain transfers electrons to the final electron acceptor?
The complex in the electron transport chain that transfers electrons to the final electron acceptor is called Complex IV, also known as cytochrome c oxidase.
What are the names of the complexes involved in the electron transport chain?
The complexes involved in the electron transport chain are named Complex I, Complex II, Complex III, Complex IV, and Complex V (also known as ATP synthase).
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.
To which component of the electron transport chain does cyanide bind?
Cyanide binds the electron transport chain at the level of complex IV
Complex IV of the electron transport chain?
Directs electron to oxygen to form water
What is the photosystem II of photosynthesis?
Splitting H2O
Which electron transport chain complex would be impaired by a deficiency of copper?
Complex IV
What is photosystem 11?
Photosystem II is a protein complex in plants and algae that is essential for the process of photosynthesis. It absorbs light energy and uses it to drive the transfer of electrons from water to plastoquinone. This eventually leads to the production of ATP and NADPH, which are important energy carriers used in the Calvin cycle to convert carbon dioxide into sugar.
