Main Difference
Both the words, Agonist and Antagonist are antonyms of each other, which are widely used in field of anatomy, biochemistry and even in literature. Although their meanings or expression vary in each of the field, but it can easily differentiate between both the terms as they are exactly opposite to each other. If one produces action, the other one opposes this action. In terms of biology, agonist and antagonist are the muscles that generally exist in pairs; bicep and tricep are one of the prominent examples of such muscles as one relaxes and the other contracts at the same time, and when one contracts the other relaxes. The term Agonist is derived from the Latin word agnista, which means ‘contender’, whereas term Antagonist has been derived from Latin and Greek words antagonista and antagonistes respectively, which means ‘competitor, rival or opponent.’
