The biochemistry lab was a section of USS Enterprise devoted to the study of biochemistry. In 2267, while all alone on the USS Enterprise after the entire ship's complement beamed down to Omicron Ceti III while under the influence of the planet's spores, Captain James T. Kirk tried to see if anyone was still on the ship by contacting engineering, ship's security and even the biochemistry lab. (TOS: "This Side of Paradise" )
