Overview of the chapter

In this chapter we will consider definitions of metabolism the biochemistry-physiology continuum. The concept of metabolic pathways and their organization and control of metabolism are likened to a road map involving flow of substrates but with mechanisms to accelerate or slow down pathways or to direct substrates through alternative routes. 

Introductions to enzyme kinetics and bioenergetics are given with explanations of key terms such as Km and Vmax coenzymes, cofactors and inhibitors typical metabolic reactions free energy exergonic and endergonic reactions, catabolism and anabolism. 

Guidance on how to study metabolic pathways is given using glycolysis as a model pathway. 

Biochemical studies follow several themes. For example, investigations can be focussed on the chemical structures of molecules, (for example the structure of glycogen, DNA or protein conformation) or the structural inter-relationship between molecules (e.g. enzymes with their substrates, hormones with their receptors). The other branch of biochemical enquiry is into those numerous dynamic events known collectively as metabolism , defined here as all of the chemical reactions and their associated energy changes occurring within cells . The purpose of metabolism is to provide the

The symposium upon which this volume is based focused on three areas in reaction engineering fluidized bed reactors, bubble column reactors, and packed bed reactors. Each area comprises a section of this book. Professor J. R. Grace chaired and coordinated the fluidized bed sessions Professors Y. T. Shah and A. Bishop, the bubble column reactor session and Professor A. Varma, the packed bed reactor session. Each section in this book opens with a brief review chapter by the session chairman that includes an overview of the chapters in each session. 

The tutorial materials provide a short overview of the chapter content, drawing attention to key concepts. The Learning Center also provides access to review materials for these concepts, using multimedia images, movies, etc.—including Chime images—to enhance and facilitate learning. Practice problems and assessment exercises provide instant feedback, to pinpoint the topics on which a student needs to spend more time. 

This first chapter provides an overview of what chemistry is about and what chemists do. The preceding What s Ahead list gives an overview of the chapter organization and of some of the ideas we will consider. As you study, keep in mind that the chemical facts and concepts you are asked to learn are not ends in themselves they are tools to help you better understand the world around you.

This is a good time to work through the appropriate chapter in the Study Guide to Chemistry. This will help you to see an overview of the chapter, to set specific study goals, and then to check and improve your grasp of basic vocabulary, concepts, and skills. Next, work the assigned exercises at the end of the chapter. 

Chapter opening sections orient the students within the larger context of physical chemistry, provide an overview of the chapter, preview the physical and mathematical relationships that will be utilized, and set defined chapter objectives.
