The function of phosphatases in signal transduction is best described as to
A) move the phosphate group of the transduction pathway to the next molecule of a series.
B) prevent a protein kinase from being reused when there is another extracellular signal.
C) amplify the transduction signal so it affects multiple transducers.
D) amplify the second messengers such as cAMP.
E) inactivate protein kinases and turn off the signal transduction.

Question

Quizplus · Accepted Answer

Phosphatases in signal transduction inactivate protein kinases and turn off the signal transduction. They remove the phosphate group from the protein, which deactivates it and stops the signal transduction.
