The specific molecules that bind to receptors are _____________(a) Ligands(b) Co-enzymes(c) Substrates(d) EnzymesThis question was posed to me by my school principal while I was bunking the class.Query is from Cellular Membranes topic in portion Cellular Membranes of Cell Biology

Answer»

The correct choice is (a) LIGANDS

To explain: Receptors present on the cellular membrane are responsible for RECEIVING the SIGNALS that come from extracellular environment. These signals are received and the corresponding action is GENERATED upon binding of specific MOLECULES called ligands on the receptors. The ligands have complementary structure with the receptors.
