Which type of molecules are involved in responding to external signals

1.	Which type of molecules are involved in responding to external signals received by the cell?(a) Enzymes(b) Nucleic acids(c) Genes(d) ReceptorsI got this question during an online exam.My query is from Cellular Membranes in chapter Cellular Membranes of Cell Biology
Answer» Right OPTION is (d) Receptors The best I can explain: Receptors present on the plasma membrane face OUTWARDS in the extracellular environment and are RESPONSIBLE for RESPONDING to signals received by cell. These signals are received in the form of small molecules that bind to the receptor consequently generating an orchestration of intracellular action.
