Department: Biological and Biomedical Sciences

BIOL1071: MOLECULAR BASIS OF LIFE

Type Open Level 1 Credits 20 Availability Available in 2009/10 Module Cap 240 Location Durham

Prerequisites

  • 'A' Level Biology OR Chemistry.

Corequisites

Excluded Combination of Modules

  • None.

Aims

  • To examine the basis for the modern, molecular approch to biology.
  • To describe the main classes of molecules found in biological systems, and their assembly into macromolecular structures such as membranes.
  • To introduce the basic concepts of cellular metabolism, and enzyme catalysis.
  • To provide an overview of catabolic and anabolic metabolism, with particular emphasis on energy generation, and examine selected pathways in detail.
  • To outline the processes of transport and signalling in cells.

Content

  • Molecules of life - basic concepts, chemical bonding and non-covalent interactions, solubility, peptides and proteins, carbohydrates, lipids, nucleic acids.
  • Membranes - composition, macromolecular structures, fluidity, transport across membranes.
  • Energy, enzymes and metabolism - thermodynamics, kinetics, enzyme catalysis, regulation.
  • Catabolism - glycolytic pathway, energy generation, fermentation, digestion.
  • Anabolism - gluconeogenesis, biosynthesis, regulation.
  • Signalling - signalling pathways, signal transduction, signalling molecules.

Learning Outcomes

Subject-specific Knowledge:
  • Appreciate the molecular basis for biological processes.
  • Understand how the functions of biological molecules and macromolecular assemblies are determined by their structures.
  • Understand basic concepts of metabolism and its analysis in terms of biochemical pathways.
  • Understand the processes of transport and signalling across cell membranes at the molecular level.
  • Appreciate the different roles played by biological molecules in the overall processes of cell function.
Subject-specific Skills:
  • Ability to understand information from appropriate sources (lectures, textbooks, online sources) relating to biochemistry of biological molecules, metabolism and its regulation, molecular processes of signalling and transport.
  • Ability to problem solve and evaluate experimental data relevant to biochemistry of biological molecules, metabolism and its regulation, molecular processes of signalling and transport.
Key Skills:
  • Interpretation and understanding of information from relevant sources (lectures, textbooks, online sources).
  • Interpretation and evaluation of data.

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

  • Lectures deliver core knowledge.
  • Lab work allows students to utilise the knowledge gained from lectures, and support the development of key and subject-specific skills.
  • MCQs sample the broad base of knowledge.
  • Unseen exams measure knowledge and the application and interpretation of that knowledge. They also test key skills in ability to present arguments and communicate them effectively in a concise written form.
  • Data handling exercises assess data handling, numeracy, critical thinking and presentation skills.
