Signal transduction cascades are produced by molecular assem

Signal transduction cascades are produced by molecular assemblies of which of the following components? Enzymes Regulatory proteins Receptors Transmembrane channels Nuclear pores

Solution

Answer : The correct answer is C (Receptors)

Explanation : Receptors are found on the plasmamembrane of the target cells which are bound by primary signal molecules called ligands/hormones. This inturn brings about the synthesis of secondary messengers such as cAMP/cGMP etc., that brings about the changes in cellular physiology through cascade of events.
