Kinase enzymes

1.remove phosphate groups.
2.always inhibit target molecule activity.
3.bind tightly by wrapping around a target molecule to regulate its activity.
4..add phosphate groups.
5.metabolize glucose.

Option D (4), add phosphate groups

Explanation:

Kinase enzymes are responsible for cellular activation. Protein kinase causes phosphorylation of specific amino acids by utilizing ATP as source of phosphate.

It adds phosphate groups (PO43−) and induces biological activity of biomolecules (such as proteins, lipids, and nucleic acids) by changing their conformation thereby activating them .

Human genome consists of several hundreds of kinase encoding genes which are involved in multiple phosphorylation reactions with in the cytoplasm of cells.  

Hence, Option D (4) is correct

he is very short, and he can only reach halfway up on the elevator buttons. but on a rainy day, he has his umbrella with him, and he uses it to poke the button at the top.
