Subject Overview:

This subject investigates the molecular mechanisms by which cells regulate their replication, function and metabolism, i.e. the essential properties of living organisms. Subject content includes an introduction to biomembranes, that create the intracellular environment and allow specific functions such as the transport of molecules and secretion of proteins. An introduction to signal transduction considers the action of hormones and cytokines that allow different cells to respond appropriately to their extracellular environment. Extracellular signals are transmitted from membrane receptors via intracellular signalling pathways to the nucleus to drive controlled expression of genes and synthesis of proteins required for cell function and metabolism, cell division (cell cycle) or cell death (apoptosis). The role of the cytoskeleton in allowing cells to maintain their shape, to migrate and to transport molecules is investigated. Nutrition and metabolism explores the dual roles of diet in providing energy and structural precursors to maintain human health. Core energy pathways relating to carbohydrate, protein and lipid metabolism will be investigated as a means of generating energy. The crucial role of cholesterol in health and disease will be considered. Hormonal regulation of metabolism critical for health and disease and the adaptations observed in fasting, starvation and in athletes will be covered. The light and dark reactions of photosynthesis are described to show how carbohydrates are made from carbon dioxide, using the energy of the sun. This elegant biochemical process is fundamental to human existence.

Learning Outcomes:

By the end of the subject the student should uderstand the following:

  • The structure and function of biomembranes e.g. in transporting molecules into or out of the cell and in protein secretion.
  • Cellular processes including cell function, cell cycling (cell division) or apoptosis as the outcome of controlled gene expression, regulated by factors within and external to cells and communicated by signal transduction molecules.
  • The cytoskeleton and cytoskeletal proteins that allow cells to maintain their shape, to migrate and to transport molecules within the cell.
  • The dual role of diet in providing energy and structural precursors for cells and to maintain human health.
  • Core metabolic pathways for carbohydrates and proteins by which cells generate ATP.
  • Signal transduction, including the action of hormones regulating metabolic pathways are critical to health and disease.
  • Photosynthesis as the crucial means by which plants generate carbohydrates from carbon dioxide, using the energy of the sun.
  • 3 hour exam held in the University examination period: 70%,
  • 2 x intrasemester test during semester (10% each): 20%,
  • Computer-based continuous assessment during semester:10%
