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.

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.
Atoms can achieve a full octet of electrons by doing what?
By bonding with another atom, either ionically (donates/receives electrons) or covalently (electron sharing).
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 do the ways in which the mass and the charge of an atom are distributed differ?
IF it donates an electron -then atom gains positive charge and if it accepts an electron then it acquires negative charge. the mass of an atom is dependent on protons and neutrons in the nucleus and electrons decide the charge of an atom
What is the function of the NADH and FADH?
They are used in the production of ATP, the 'energy currency' of the cell. FADH2 and NADH have the very important role of being electron carriers for the electron transport chain. Both are used at key points in glycolysis and/or the Kreb's cycle. FADH2 : Carries electrons in the form of hydrogen atoms (1 proton and 1 electron) with 0 net charge. With 2 hydrogens FAD may use these electrons one at a time or 2 at a time, depending on which ever process it is in. NADH : Carries it's electrons in the form of hydrides (1 proton and 2 electrons) with -1 net charge. Since these electrons are in the hydride form they both must be used at the same time, there isn't an option to use 1 OR 2 only 2 electrons.
During aerobic respiration what directly donates electrons to the electron transport chain at the lowest energy level?
FADH2 Only FADH2 and NADH donates electrons to the electron chain, and FADH2 donates at a lower level. Hence FADH2 produces less ATP than NADH.
When a compound donates electrons the compound becomes what?
if a neutral atom donates an electron it will gain a positive charge. This is due to electrons having a negative charge.
What molecule donates the second h plus and e plus to the electron transport chain?
y
Does sodium chloride share electrons?
Actually, sodium almost donates an electron to chlorine in NaCl.

Lithium has one valence electron Bromine has seven valence electrons How might they form a chemical bond?
lithium donates an electron to bromine
Did sodium donates or accept electrons?
Sodium donates one electron from it's valance shell and becomes the cation, Na + Having a 1 + positive charge as it is short the one electron.
Which of the following statements regarding events in the functioning of photosystem II is false?
The P680 chlorophyll donates a pair of protons to NADPH, which is thus converted to NADP+
Atoms can achieve a full octet of electrons by doing what?

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 do lithium and fluorine become stable together?
lithium donates the electron in its outer orbital to fluorine which then has a completed outer shell
In the light reaction what is the electron donor where do the electrons end up?
water donates the electrons when H2O is separated into 2 hydrogen and one oxygen by the water-splitting enzyme in photosystem II. The electrons then enter the electron transport chain, entering a hydrogen pump which uses energy to push hydrogen into the thylocoid. Electrons get recharged in the next chlorophyll almost like a battery, finally they combine with NADP+ and a hydrogen to create NADPH. btw, two electrons are donated per H2O molecule
