Based on what you know about types of reactions and enzyme regulation, what can you conclude about the chemical reaction catalyzed by a protein kinase?

1.The energy change in this reaction is negative.
2.This reaction is common in allosteric regulation of enzymes.
3.The chemical reaction catalyzed by a protein kinase is a dephosphorylation reaction.
4.The chemical reaction catalyzed by a protein kinase is an endergonic reaction.

Solution

Based on what you know about types of reactions and enzyme regulation, what can you conclude about the chemical reaction catalyzed by a protein kinase?-

ans-

1.The energy change in this reaction is negative.

(protein kinase is a enzyme that involves in adding phosphate groups to other protein called phosphorylation.

in phosphorylataion-

. Phosphorylation is irreversible.

ATP is the energy needed, and thus it links the process to bio energetics.)
