Molecules that furnish electrons during a chemical reaction are called?
Molecules that furnish electrons during a chemical reaction are called reducing agents or electron donors. These molecules undergo oxidation as they donate electrons to another molecule, known as the oxidizing agent or electron acceptor.
When an electron is passed to an electron acceptor molecule such as NADP what happens to NADP?
NADP becomes reduced to form NADPH when it accepts an electron from an electron donor, such as an electron. This reduction reaction allows NADP to carry high-energy electrons for use in cellular processes like photosynthesis.
How does dcpip in the hill reaction affect absorbance?
DCPIP is a blue colour when its oxidized and when it is reduced it turns into a colourless solution. DCPIP replaces NADPH the final electron acceptor in the light dependent reaction. So basically, as the reaction continues, the more DCPIP is reduced and the absorbance decreases.
What happens in a Lewis acid-base reaction?
An acid accepts an electron pair from a base.
What is the purpose of the 2e- in the balanced equation above?
No equation above, but this is an example.2H+ + 2e- + 1/2O2 --> H2OThis is the equation, of the electron transport chain, that shows the final electron acceptor, oxygen, taking two protons and two electrons and forming water.This,2e-represents the two electrons and the negative charge they carry.
What is the difference between an electron donor and electron acceptor?
Donor atoms are atoms that donate electrons and have an extra pair of electrons in their orbital. Acceptor atoms are atoms that accept electrons and have a empty orbital to accommodate the extra electrons.
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.

When a compound serves as an electron acceptor it is oxidized?
No gain of electron is reduction. An atom that gains electrons is reduced in a chemical reaction. OIL RIG; oxidation is loss, reduction is gain
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.
NADPH is formed when the electrons acceptor NAPD combines with what?
NADPH is formed when the electron acceptor NADP+ combines with electrons and a hydrogen ion (H+). This reduction reaction takes place during the light reactions of photosynthesis, where energy from sunlight is used to drive the electron transport chain and ultimately produce NADPH.
Is tin an electron donor or an electron taker?
Tin can act as both an electron donor and an electron acceptor, depending on the chemical reaction it is involved in. In some reactions, tin can donate electrons to other elements, while in others, it can accept electrons.
What charge is on acceptor atom?
If I understand it right, an acceptor atom is that one which accepts the electrons, then it has positive charge and thus it is able to attract the negatively charged electrons.
What does a phtosystem contain?
Photosystem is composed of pigments, reaction center and electron acceptor
