The setup described here for recording chemical transient phenomena is intended to be simple and an instructive example of interfacing experiments that can be performed on any microcomputer possessing adequate memory and input-output facilities. (BB)

A practical exercise is described that allows students to investigate a specific problem using a variety of biochemical techniques. The need for a thorough understanding of the theoretical principles underlying these processes is emphasized. A program of private study and assessment is suggested to enable the progress of students to be followed.…
