Modules

BIO1023 : Cells and Biomolecules

Semesters
Semester 1 Credit Value: 20
ECTS Credits: 10.0

Aims

The module aims to enable students to appreciate the fundamental importance of cellular and biochemical processes for whatever aspect of biology they subsequently specialise in. It aims to provide basic information about: (i) eukaryotic cells and their organisation; (ii) the major biological macromolecules; (iii) how structures and functions of cells and biomolecules relate to each other; and (iv) how biomolecules are synthesised and degraded through central metabolic pathways and the links to production and use of energy. It also provides the opportunity for students to gain hands-on experience of studying cells and biomolecules and to develop skills needed to work effectively in a laboratory, perform relevant calculations, display and interpret experimental results and prepare laboratory reports.

Outline Of Syllabus

Lectures:

Introduction
Methods of studying cells
Macromolecules and their constituents:
• Proteins as enzymes and structural molecules
• Carbohydrates as structural and storage molecules
Lipids and membranes
Integration of eukaryotic cells: the endomembrane system, the cytoskeleton and cell connections
Cellular processes: motility, cell division
Metabolic processes:
• Energy generation by glycolysis, fermentation and respiration
• Anabolic pathways: the pentose phosphate pathway, gluconeogenesis
• Photosynthesis
• Lipid breakdown and synthesis
• The nitrogen cycle
Research seminars: cover relevant current research topics, reinforcing material covered during lectures and helping students to appreciate the importance of research on cells and biomolecules across the life sciences.

Practicals:

Cell structure
Properties of proteins
Enzyme activity
Photosynthesis

On-line material:

Basics of chemistry

Teaching Rationale And Relationship

Lectures will provide students with the essential factual and conceptual information for the module. The practical classes give students the opportunity for hands-on study of cells and biomolecules, developing their skills in using laboratory equipment and in collecting, manipulating (including numerical calculations), presenting and interpreting experimental data. On-line material will be provided for students who need to gain confidence with or to revise basic chemical principles.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The formal examination will assess the breadth of students’ knowledge of material covered in the module through a mixture of short answer (such as fill in blanks, multiple choice, label diagrams, draw structures) questions and the depth of their knowledge through short essay answers on specific topics.

Assessment of laboratory reports will appraise data collection, presentation and numerical manipulation skills, and the ability to link results of practical experiments to theoretical knowledge. The Blackboard self-test quiz will help students to review and assess what they have learned from the seminars.

Formative assessment through practice lab reports will help students prepare for the summatively assessed reports and for the exam by allowing them to gauge their preparedness and identify where improvement is needed.

Study Abroad students may request to take their exam before the semester 1 exam period, in which case the format of the paper may differ from that shown in the MOF. Study Abroad students should contact the school to discuss.
