Objectives

Learning outcomes
On completion of this module students will be able to;
- describe the architecture of membranes and identify the processes that lead to the biosynthesis and assembly of individual components (membrane lipid biosynthesis, insertion and integration: membrane protein biosynthesis, modification and targeting, enzyme complexes);
- appreciate that membranes are dynamic structures which separate and regulate cellular compartments;
- identify the mechanisms by which ionic gradients are established and utilised;
- appreciate the characteristics of the multi-subunit complexes that facilitate electron transfer either in metabolism and photosynthesis;
- describe the properties of different types of membrane proteins that act as receptors and those which act as transporters, using illustrative examples;
- investigate the transport mechanisms involved in the uptake of metabolites by cells;
- describe the components within generic and specific eukaryotic cell signalling pathways activated by extracellular signals;
- contrast the cellular perception and intracellular action of nuclear hormones with that of hormones acting via cell surface receptors;
- construct an example of an integrated signal transduction pathway detailing the components involved with time following the detection of an extracellular signal;
- explain how G-proteins, protein kinases, protein phosphatases, cyclic nucleotides, calcium ions and lipid-derived mediators act as signal modulators.


Syllabus

This module will cover:
1) Biological membranes
- the architecture and dynamics of biological membranes
- the processes that lead to the biosynthesis and assembly of individual components (membrane lipid biosynthesis, insertion and integration: membrane protein biosynthesis, modification and targeting, enzyme complexes).

2) Membrane transport
- the characteristics of the multi-subunit complexes that facilitate electron and proton transfer either in metabolism and photosynthesis;
- the transport mechanisms involved in the uptake of metabolites or by cells;
- the mechanism of ion channels.

3) Cell signalling
- the components within generic and specific eukaryotic cell signalling pathways and the activation of these pathways by extracellular signals (G-proteins, protein kinases, protein phosphatases, cyclic nucleotides, calcium ions and lipid-derived mediators);
- cellular perception and intracellular action of nuclear hormones.

The module consists of 20 1-hour lectures. For each 1-hour lecture, a further 4 hours of reading, self study and self-assessment are required.

Opportunities for Formative Feedback

The module contains an assessed MRQ in week 10 and several self-assessed (VLE-based) or formatively assessed MRQs that are released during the module.
