What happens with FADH2 donates its electrons to the electron transport chain and what are the final products?

Complex II is reduced and FADH2 is oxidized becoming FAD, the electrons continue down the electron transport chain providing the power to pump protons into the intermembrane space ( not as many protons as NADH because of the short delivery of FADH2 electrons to complex II ) where they fall down their concentration gradient through the synthase. Our electrons exit complex IV into the matrix where oxygen picks up two electrons and two protons forming water. 2H + 1/2O2 --> H2O.

What is the reaction when chlorophyll donates excited electrons?
the reaction center.
How are NADH and FADH2 related?
NADH and FADH2 are both electron carriers involved in cellular respiration. They donate electrons to the electron transport chain to generate ATP. NADH donates electrons at complex I, while FADH2 donates electrons at complex II of the electron transport chain.
How many valance electrons are there in Fr plus?
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
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.
If an atom donates or accepts an electron what is it considered?
If an atom donates or accepts an electron it is considered an ion.
How many electrons can a NADH molecule carry?
A NADH molecule can carry two electrons. The molecule donates these electrons to the electron transport chain during cellular respiration to generate ATP.
During aerobic respiration what directly donates electrons to the electron transport chain at the lowest energy level?
NADH and FADH2 donate electrons to the electron transport chain at the lowest energy level during aerobic respiration. These molecules are produced during earlier stages of cellular respiration (glycolysis and the citric acid cycle) and deliver high-energy electrons to the electron transport chain for ATP production.
When a compound donates electrons the compound becomes what?
When a compound donates electrons, it becomes oxidized. Oxidation involves a loss of electrons.
What is the reaction when chlorophyll donates excited electrons?
the reaction center.
How are NADH and FADH2 related?
NADH and FADH2 are both electron carriers involved in cellular respiration. They donate electrons to the electron transport chain to generate ATP. NADH donates electrons at complex I, while FADH2 donates electrons at complex II of the electron transport chain.
What molecule donates the second h plus and e plus to the electron transport chain?
y
What is electron donor?
An electron donor is a substance that donates electrons to another substance during a chemical reaction, typically becoming oxidized in the process. In biological systems, molecules like NADH or FADH2 are electron donors that transfer electrons to the electron transport chain.
Did sodium donates or accept electrons?
Sodium typically donates electrons to become a positively charged ion, Na+. It has one electron in its outer shell, which it tends to give away to achieve a stable electron configuration.
How many valance electrons are there in Fr plus?
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
Does sodium chloride share electrons?
No, sodium chloride does not share electrons. It is an ionic compound formed by the transfer of electrons from sodium to chlorine, resulting in the formation of Na+ and Cl- ions which are held together by electrostatic forces.
Is zinc an electron donor or acceptor?
Zinc is an electron donor. It typically donates electrons in chemical reactions to form stable compounds.
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.
