600-131 Biomed: Molecules, Cells & Organisms

• This subject is only available to Bachelor of Biomedical Science students.

• Experiments involving the use of animals are an essential part of this subject; exemption from these experiments is not possible.

• Credit cannot be gained for this subject and 600-141.

• This is a joint botany and zoology subject.

Students are expected to enrol in both 600-131 and 600-132

This subject aims to familiarise students with modern concepts of molecular, cell and organismal biology as a foundation for further studies in biomedical science. Two major topics are addressed. Cell and molecular biology includes the chemical building blocks of life, functioning cells, cell evolution and endosymbiosis; cell organelles, their structure and function; movement across membranes: structure, permeability and transport; the cell wall and extracellular matrix; cell metabolism: enzymes and cellular reactions; excitable cells; energy transformations; cell divisions: mitosis and meiosis; cells and tissues; cellular communication and signalling; tissue culture and cloning. Animal physiology includes a comparative approach to circulation, nutrition and digestion, excretion, respiration and gaseous exchange, thermoregulation, reproduction, development, the immune system, hormonal control and nervous systems.

Students will develop generic skills in:

• dissection techniques and the preparation of slides;

• the recording of observations and the analysis and interpretation of data;

• the preparation of biological drawings;

• manipulating laboratory equipment, in particular using microscopes; and

• accessing information sources and discerning use of the world wide web.

A 3-hour written examination on theory and practical components of the subject at the end of semester, practical assessment and mid-semester tests. Satisfactory performance in the practical assessment is a hurdle requirement for passing the subject.
