Exclusions
Description This course aims to illustrate the pivotal role of biological membranes in the cell physiology of prokaryotes and eukaryotes, including both plant and animal cells. Lectures and student-centred activities will explore this subject under three broad themes.
1) The role and properties of membranes: lipid and protein components; how membranes define compartments; techniques and methodologies.
2) Energy generation within the cell: electron-transfer pathways; generation of ATP; oxidative phosphorylation and photosynthesis.
3) Metabolism: gluconeogenesis and the pentose phosphate pathway; the Calvin cycle; regulatory mechanisms and the control of metabolic pathways; the influence of hormones and other factors.
Learning Outcomes

By the end of the module students should be able to:

  • explain the principles of membrane fusion and give an account of the various methods used to study membranes;
  • calculate bioenergetic parameters based upon redox values and other types of data;
  • describe the properties and functions of electron transfer pathways and their protein and redox components;
  • explain the integration of anabolic metabolism with photosynthesis and energy metabolism;
  • compare and contrast microbial energy systems with those of eukaryotes;
  • recall the metabolic pathways and discuss how they function within the cell;
  • explain the concepts of allostery, metabolic flux, and hormonal regulation of metabolism.

In addition, through participation in practical classes, workshops and group work, students should be able to:

  • follow experimental protocols to investigate enzyme catalysed cleavage of phospholipids, lipid separation and redox reactions;
  • record and analyse experimental TLC and redox potential data;
  • complete lab reports on the module experiments, evaluate data and draw conclusions;
  • analyse data from bioenergetics and membrane studies by tackling problem-based questions.
