Question

Quizplus · Accepted Answer

All of the choices provide amplification of hormone action in the cell. Production of second messengers amplifies signal transduction by amplifying the original signal. Kinase cascades amplify the signal by propagating the signal through multiple kinase reactions. Activation of G proteins amplifies the signal by activating multiple downstream effectors.
