Discusses how instruction of biological concepts as ATP cellular energetics is related to fundamental physical science understandings. Reviews areas of common misconceptions and confusions. Summarizes results of a study which investigated students' knowledge and perception of difficulty associated with the topic of energy and ATP. (ML)

Guidelines developed by the Sections of Biochemistry and Nutrition and Dental Hygiene Education of the American Association of Dental Schools are intended for use by individual educational institutions as curriculum development aids. (MLW)

A simple, rapid, and safe method has been developed for disrupting bacterial cells for protein studies. The method involved stepwise treatment of cells with acetone and with sodium dodecyl sulfate solution to allow extraction of cellular proteins for analysis by polyacrylamide gel electrophoresis. Applications for instructional purposes are noted.…

Outlines a simple but rigorous treatment of the Krebs Cycle suitable for A-level Biology students. The importance of the addition of water molecules in various stages of the cycle is stressed as well as the removal of hydrogen atoms by the oxidizing enzymes. (JN)

Outlined are the history, programs, and staff of the Max Planck Institute for Biophysical Chemistry in Gottingen, West Germany. (SL)

A personalized account of some experiences in the Department of Biochemistry at the University of Dundee during a radical revision of the course for medical students is offered. Innovations of the course are described in detail. (LBH)

The two-credit, one-semester course was initiated for fourth-year pharmacy students at the University of Nebraska Medical Center. It was organized to enable the student to better understand the health problems of the patient and to better communicate information on drugs to patients and health professionals. (LBH)

Test performance and attitudes of freshman medical students exposed to various methods of instruction in a biochemistry laboratory are compared. (Editor)

Experiments conducted on wheat and barley grains to analyze activities of alpha- and beta-amylase enzymes. Gibberellins were used exogenously. Techniques are described in detail. Results on different cultivars revealed that beta-amylase was not an invariable result of imbibition. Techniques employed can be used by school students. (PS)

The Space Shuttle Program is aimed at not only providing low cost transportation to and from near earth orbit, but also to conduct important biological research. Fields of research identified include gravitational biology, biological rhythms, and radiation biology. (PS)

The continuous measurement of oxygen consumption in an enzymatic reaction is a frequent experimental fact and extremely important in the enzymatic activity of oxygenase. An electrochemical system, based on a polarographic method, has been developed to monitor the oxygen uptake. The system developed and electrode used are described. (JN)

Describes an inexpensive, easily constructed, and safe vertical slab gel kit used routinely for sodium dodecyl sulphate-polyacrylamide gel electrophoresis research and student experiments. Five kits are run from a single transformer. Because toxic solutions are used, students are given plastic gloves and closely supervised during laboratory…

Describes a low-cost, high-voltage, two-terminal, constant-current source for student use in electrophoresis experiments (includes circuit diagram) and a simple device for the continuous registering of gas flows. Also lists seven cost-saving tips for chemical reagent, including use decorative stones (purchased from nursery stores) in place of…
