Answer: Every enzyme has a specific name that can give us insight into the specific reaction that that enzyme can catalyze. We divide them into six different categories.
1) Oxidoreductase - includes two different types of reactions by transferring electrons from either molecule A to B or vice versa. It is involved in oxidizing electrons away from a molecule.
2) Hydrolase - uses water to divide a molecule into two other molecules.
3) Transferase - you move some functional group X from molecule B to molecule A
4) Ligase - catalyzes reactions between two molecules, A and B, that are combining to form a complex between the two. (example: DNA replication)
5) Lyase - divides a molecule into two other molecules without using water and without reducing or oxidation
Answer:
the correct option is D.
Explanation:
ionic bond:
ionic bond is a bond where one of the atom donates one or two electron to one or more than one atom for all the atom to attain stability that is octet.
chlorine has 17 electrons so the outer most orbit has 7 electron for it to obtain stability it has to gain one more electron while magnesium has 12 electrons so it has to lose 2 electrons to gain stability so if a magnesium atom loses 2 of its electron to two chlorine atoms botn the chlorine will have 18 electron and magnesium will have 10 electron therefore every atom attaining octet. by this way magnesium forms ionic bond with two chlorine atom to form MgCl2.
so option d must be correct.
