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.


What is the electron donor molecule called?

A molecule which donates electron(s) to an other, is called a reductor orreducing atom / moleculeExample:2Fe --> 2Fe2+ + 4 e- reductor Fe4 e- + O2 --> 2O2- oxidator O2-------------------------------------------- +2Fe + O2 --> 2FeO redox reaction, the corrosion of Iron by Oxygen (forming rust)


How does a nucleophile donate electrons in a chemical reaction?

A nucleophile donates electrons in a chemical reaction by using its electron-rich atoms to form a bond with an electron-deficient atom or molecule. This donation of electrons helps to stabilize the resulting compound and drive the reaction forward.


When the energy of sunlight moves to a chlorophyll molecule in a reaction center how does this impact an electron?

Electrons absorb the energy. Then it becomes exited

Which high-energy molecule and electron carrier are produced by the light reaction of photosynthesis?

NADPH and ATP are produced by the light reactions. The ATP is a high energy molecule produced by photophosphorylation while the NADPH is produced at the end of the electron transport chain.


What is the difference between oxidation and hydrolysis?

Oxidation is a reaction in which an atom, molecule or compound loses an electron. OIL = Oxidation Is Lost; RIG= Reduction Is Gain LEO = Lose Electron in Oxidation; GER = Gain Electron in Reduction (LEO the lion says GER) Hydrolysis is a reaction in which a molecule or compound is broken down, by the addition of a water molecule (it is NOT the breaking of a water molecule into oxygen and hydrogen - that is a different reaction called electrolysis). An example of hydrolysis is the breaking down of maltose into 2 glucose molecules. A molecule of water is added, usually with an acid to catalyse the reaction, into a solution of maltose. You can therefore say that hydrolysis is a type of oxidation reaction, being as maltose loses glucose molecule (hence losing the electrons in the atoms of glucose).


A molecule that gives up an electron becomes what?

Oxidized.Oxidation involves a loss of electrons.The answer above in a general context is wrong I'm afraid - If an atom loses an electron it becomes an ion and the same if it gains one - and electrically charged particle.
