Photoexcitation<span> is the photoelectrochemical process of electron excitation by photon absorption, when the energy of the photon is too low to cause photoionization. The absorption of the photon takes place in accordance with Planck's quantum theory.</span>
The macromolecule would be glucose (sugar). C6H12O6
Answer: Option D.
The transfer of the methyl group from adomet to an acceptor yields s adenosylhomocysteine.
Explanation:
S- adenosine methionine is a co substrate and one of the naturally occurring sulfonium ions in the body. It is synthesized from methionine which is abundant in animal derived protein. It is metabolised in the liver where it is converted to S adenosine methionine by the enzyme methionine adenosyltransferase. It involve the transfer of methyl group. It is use in medicine as alternative aid to reduce depression.
