B. D. Sharma Postgraduate Institute of Medical Sciences (PGIMS), Rohtak, Haryana, India as a Professor and Nodal Officer at the Multidisciplinary Research Unit of the Institute. The first textbook on Biochemistry was written by Alexander Thomas Cameron in 1928. Since then, ginormous development has taken place in the field of Biochemistry into different scientific canals. On one hand the whole genome has been unfurled and on other hand, there has been great demand of traditional knowledge. When the world is passing through turmoil of knowledge bank, there has been great development in understanding the ‘Chemistry of Biological Systems’. Professor Simmi Kharb has generated literature by virtue of her book in the arena of Biochemistry with an aim (ambition in mind) that the present day students studying Biochemistry need comprehensive information at one place in understandable language that can act as unstoppable orientation in young minds that would lead to formation of strong grass root for becoming passionate Biochemists. It was being felt by the teachers and students of Biochemistry that a composite collection of Biochemical Principles which can find place in the minds of learners just like map, was missing in the literate world. Dr. Simmi Kharb accepted the challenge of producing a book on Biochemistry that has simple, consolidated, easy to read and retain, all in one, mixture of basic and advanced knowledge module. The issues covered in this book are: Biochemical concepts, Organization of chemical and biological approach, Principles in balance of biological systems, Acquiring meaningful understanding of Biochemistry, Real-time world relevance and Problem-solving mechanisms. The book runs through cell to body. ii I am confident that this book shall make its place in libraries, minds of teachers and vocal cord of students all over the world. Gajendra Singh, Ph.D Professor and Dean Faculty of Pharmaceutical Sciences Pt. BD Sharma University of Health Sciences Rohtak 124001 Haryana India iii PREFACE Students often view Biochemistry as a pile of facts or equations to be memorized rather than as concepts to be understood. The author proposes to create a series of concept and knowledge maps about the biochemical contents to illustrate graphically the relationships between the ideas presented in a given proposed chapter, as well as to show how information can be grouped or organized. In order to facilitate the student’s understanding of the metabolic pathways and providing greater interaction with the contents, an approach to better learning metabolic diagrams will be developed through: i. Flow diagrams and illustrations: showing substrates and enzymes of the metabolic pathways, their control, inhibition, role of vitamins in their correct functioning, and their connection with other systems ii. Reading the functions and characteristics of metabolic pathways in illustrations iii. Solving of essay and multiple-choice questions iv. Recent advances and applied aspects of biochemistry, applied therapeutics and microbiology will be discussed Also, students will be encouraged to make their own flow diagrams and tables and sample questions will be provided to improve their analytical skills. As a learning tool, it can be used by the student to, e.g., making notes, solving problems, planning the study and/or writing of essays, preparing for examinations, and identifying the connection of topics. ACKNOWLEDGMENT & CONFLICT OF INTEREST No potential conflict of interest is declared by the author. It is also declared the complete work is an individual effort by the author and there was no financial/ administrative/ academic support availed from any individual/ institution /organization.

Prokaryotic cell, Plasma  Appraise the structure and function of the cell membrane. membrane, Passive transport, Sub-  Explain the transport mechanisms operating across the cellular component. plasma membrane. KEY FEATURES OF CELL Cells possess a genetic program and the mean to use it: capable of producing more of themselves. 1. Cell: structural and functional unit of life. Cells acquire and utilize energy, carry out a variety of chemical reactions: metabolism. 2. Most chemical reactions take place within cells. Cells engage in mechanical activity able to respond to stimulant. 3. Cells are of two types: PROKARYOTIC CELL i. Prokaryotic cell Lack well-defined nucleus. ii. Eukaryotic cell Contain rigid cell wall. - The human body is composed of 1014 cells. EUKARYOTIC CELL Cells are highly complex and organized. Contain well defined nucleus, more complicated internal structure.
