Dephosphorylation in the transuction process needs:
A) protein kinases
B) protein phosphatases
C) single sugar like glucose
D)cabohydrate
The correct answer is B) protein phosphatases.
To understand why protein phosphatases are needed for dephosphorylation in the transduction process, let's break it down:
1. Transduction process: Transduction is the process by which signals are transmitted from the extracellular environment to the intracellular environment. It involves a series of molecular events, including the activation or deactivation of signaling proteins.
2. Phosphorylation: Phosphorylation is a common post-translational modification that involves the addition of a phosphate group to a protein. This modification can either activate or deactivate the protein, depending on the signaling pathway.
3. Dephosphorylation: Dephosphorylation is the process of removing the phosphate group from a protein. It is necessary to revert the protein to its inactive state or inactivate the signaling pathway.
4. Protein phosphatases: Protein phosphatases are enzymes responsible for catalyzing the removal of phosphate groups from proteins, thereby promoting dephosphorylation. They play a critical role in regulating cellular processes by counterbalancing the activity of protein kinases, which add phosphate groups.
So, in summary, dephosphorylation in the transduction process requires protein phosphatases (option B) to remove the phosphate groups from proteins and deactivate the signaling pathways.
