Question

Protein kinases are responsible for transferring which group?

(a) oxygen

(b) carbon

(c) amino

(d) phosphate

I got this question by my school principal while I was bunking the class.

My doubt stems from Metabolism topic in section Bioenergetics, Enzymes, Metabolism, Genes, Chromosomes and Genomes of Cell Biology

Answer 1

Right choice is (d) phosphate

To elaborate: Protein kinases are a class of enzymes that transfer phosphate group to other proteins (covalent modification). These are hence vital in hormone action, cell division and gene expression.
