Which statement regarding phosphoryl group transfers is true?

The enzymes that catalyze these reactions using ATP are known as kinases.

Phosphoryl groups are poor leaving groups.

Phosphate has two resonance structures.

Phosphorus can only form four covalent bonds.

Option (1).

Explanation:

ATP (adenosine triphosphate) is the energy currency of the cell. The ATP molecule is hydrolyzes into ADP (adenosine diphosphate) and the inorganic phosphate.

Kinases are the enzymes that are known to add the phosphate group on the substrate. These kinases works in the energy dependent manner and require ATP for its reaction. The phosphate group can be transferred from one molecule to the other molecule as well.

Thus, the correct answer is option (1).

Answer: I think it's the second one
