Which statement about an agonist and an antagonist of the same receptor is correct?
ABoth bind the receptor, but the antagonist gives the larger response
BThe agonist binds enzymes while the antagonist binds receptors
CThe antagonist stops the messenger from being synthesised
DBoth bind the receptor, but only the agonist produces the receptor's response
