Human Biochemistry (BCHM2072)

UNIT OF STUDY

This unit of study aims to describe how cells work at the molecular level, with a special emphasis on human biochemistry. The chemical reactions that occur inside cells are described in the first series of lectures, Cellular Metabolism. Aspects of the molecular architecture of cells that enable them to transduce messages and communicate with each other are described in the second half of the unit of study, Signal Transduction. At every stage there is emphasis on the 'whole body' consequences of reactions, pathways and processes. Cellular Metabolism describes how cells extract energy from fuel molecules like fatty acids and carbohydrates, how the body controls the rate of fuel utilisation and how the mix of fuels is regulated (especially under different physiological circumstances such as starvation and exercise). The metabolic inter-relationships of the muscle, brain, adipose tissue and liver and the role of hormones in coordinating tissue metabolic relationships is discussed. The unit also discusses how the body lays down and stores vital fuel reserves such as fat and glycogen, how hormones modulate fuel partitioning between tissues and the strategies involved in digestion and absorption and transport of nutrients. Signal Transduction covers how communication across membranes occurs (i.e. via surface receptors and signaling cascades). This allows detailed molecular discussion of the mechanism of hormone action and intracellular process targeting. The practical component complements the lectures by exposing students to experiments that investigate the measurement of glucose utilisation using radioactive tracers and the design of biochemical assay systems. During the unit of study, generic skills are nurtured by frequent use of analytical and problem solving activities. Opportunities are provided to redesign and repeat experiments so as to provide a genuine research experience. Student exposure to generic skills will be extended by the introduction of exercises designed to teach oral communication, instruction writing and planning skills.
