Reviews the main principles of interfacing and discusses the software developed to perform kinetic data capture and analysis with a BBC microcomputer linked to a recording spectrophotometer. Focuses on the steps in software development. Includes results of a lactate dehydrogenase assay. (ML)

Discusses a simulation on enzyme kinetics based upon the ability of computers to generate random numbers. The program includes: (1) enzyme catalysis in a restricted two-dimensional grid; (2) visual representation of catalysis; and (3) storage and manipulation of data. Suggested applications and conclusions are also discussed. (DH)

A brief review of the mole concept and its application is given, major problem areas are highlighted, and suggestions are made for a unified approach to alleviate some of the student misunderstanding when preparing solutions, calculating concentrations, and determining effects of dilution.
