Examines the influence of enzyme and substrate concentrations, pH, temperature, and inhibitors on catalytic activity. Follows the influence of different phosphate concentrations in the growth medium on enzyme activity. Studies regulation of enzyme synthesis by repression. Includes methodology for six experiments. (MVL)

Offers several advantages over other possibilities as the enzyme of choice for a student's first exposure to a purification scheme. Uses equipment and materials normally found in biochemistry laboratories. Incorporates several important biochemical techniques including spectrophotometry, chromatography, centrifugation, and electrophoresis. (MVL)

Describes a simple method for purifying catalase for the study of proteins. Procedures are systematically and diagramatically presented. Also identifies polyacrylamide gel electrophoresis, kinetic studies, and apparent molecular weight determination as possible techniques to be used in studying proteins. (ML)

Describes six demonstrations used in a medical biochemistry course. These demonstrations focus on: (1) platelet aggregometry; (2) ion-transporting antibiotics; (3) glycosylated hemoglobin; (4) molecular models; (5) serum preparation; and (6) bioluminescence. (JN)

Describes how a computer simulation is used with a laboratory experiment on the synthesis of urea in isolated hepatocytes. The simulation calculates the amount of urea formed and the amount of ammonium remaining as the concentrations of ornithine, citrulline, argininosuccinate, arginine, and aspartate are altered. (JN)

Background information, experimental approach, materials needed, procedures used, and typical results obtained are provided for genetic engineering experiments. The course in which these experiments are performed is also described. (JN)

Describes an experiment which allows students to identify the nature of the time-course for chymotrypsin and to obtain mechanistic information on the two kinetic phases in terms of their concentration dependence. Also describes the computer simulation (available from the author) used in the experiment. (JN)

Background information, procedures used, typical results obtained, and calculations are provided for a short (4-6 hours) kinetic experiment which includes different methods both in performance and in analysis of the results. The experiment can be modified and extended depending on the level of students and the available laboratory time. (JN)

Presents a hand-out given to students at the University of Canterbury, New Zealand, concerning expectations and guidelines for finishing laboratory reports. Topics covered are accuracy, data collection, and write-up format that includes introduction, materials utilized, procedures, results, discussion, conclusion, tables and illustrations, units…

Reports on the development of a modified Problem-Based Learning approach to a freshman course. Enables faculty to teach basic biochemical concepts and principles as well as their application to clinical cases. Includes the syllabus and workshop goals based on Bloom's taxonomy. (MVL)
