Described is the first part of a two-term project involving final-year students in biochemistry. Listed are the required experiments compiled to test students' abilities to search biochemical literature, extract experiments from journals and carry them out, generate data, and interpret results. (CS)

Steps for developing a program to compute peak blood alcohol levels are offered. A review of the Diet Inventory Nutritional Experiences (DINE) System explores a computerized nutrition program. (DF)

Presented is one of a series of articles designed to help science teachers keep current on ideas in specific areas of biology. This article provides information about ion transport in plant cells. (PB)

Discussed is the fundamental role that the favorable free energy of binding of the rate-determining transition state plays in catalysis. The principle that all of the catalytic factors discussed are realized by the use of this binding energy is reviewed. (CW)

A method of obtaining a crude mitochondrial extract from sheep and beef heart is described. The respiratory substrates succinate and malate are examined as well as the inhibitory effect of malonate. An interface with a microcomputer for plotting colorimeter results is discussed. (Author/CW)

Presented is one of a series of articles designed to help science teachers keep current on ideas in specific areas in biology. Contained is information on how plants use light for growth, seed germination, and flowering. (PB)

Presented are three ways in which bioactivity of organic compounds has been introduced in organic chemistry courses. One is to point out a typical bioactivity of a given functional group. A second is to discuss biorganic mechanisms. A third is to draw structure-activity correlations (SAR). (Author/HM)

Two new packages designed to aid students in typical undergraduate biochemistry courses are described. These packages deal with alcoholic fermentation and the reversal of glycolysis and the reactions of the citric cycle. (MP)

This guide is intended to provide stimuli for discussion and review of ecological principles and their relevance to daily human existence. The illustrations, purposefully detailed and complex, are intended to provide a basis for in-depth discussion. The bulletin is intended to supplement classroom materials and also to serve non-classroom…

Described are the composition, design, administration, and evaluation of practical examinations. A table of the composition of biochemical unknowns for analysis in practical examinations is included. (CW)

Experiments designed to help undergraduate students gain experience operating instruments and interpreting gas chromatography and mass spectrometry data are presented. Experimental reagents, procedures, analysis, and probable results are discussed. (CW)

The need to give high school students a more pragmatic grasp and understanding of technology, in addition to guidance concerning their career paths, is discussed. Described are the design, initiation, methods, topics and evaluation of this exploratory program. Recommendations for future implementation of similar programs are provided. (CW)

Described is an experiment which is designed to investigate the reaction of the protein ferrimyoglobin with fluoride. The activity uses readily available apparatus and the technique of optical absorbance for measurement of concentrations. Experimental design, procedures, and treatment of the equilibrium data are detailed. (CW)

Intended to help foreign students in their study of chemistry in the United States, this guide begins with an overview of chemical education at primary, secondary, and college levels, typical curriculum for undergraduate chemistry degrees (including calculation of honor point average), and an overview of graduate training (admissions,…

This guide provides a detailed look at the biological basis of drug addiction, examining how the brain and its reward system work and how drug abuse can cause fundamental changes in the way the brain works. It is a resource for clinicians and practitioners. The first section of the guide provides an outline of the following basic concepts…
