Why Would A Signaling Pathway Need To Be Regulated

5. What determines where a protein kinase or protein phosphatase will perform its enzymatic activity?
Answer:
As protein kinase and protein phosphatase are the enzymes, they both perform their enzymatic activity by interacting at the specific binding site on the protein. Both of the enzymes recognize the specific amino acid sequence around the amino acid that is to be either phosphorylated or dephosphorylated respectively.
6. Why would a signaling pathway need to be regulated?
Answer:
Signaling pathway needs to be regulated because if not regulated, it would leads to excess response to certain stimulus. This would results in unbalanced of homeostasis in the body and thus would leads to different diseases, infections, and inflammation
