This course involves four hours a week of classroom instruction, including lectures and tutorials in which selected problems from the textbook are collectively solved.
Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:
|Two term examinations||30-50%|
|One final examination||30-40%|
Upon completion of Biology 2421, the student will be able to:
- Describe the chemistry of water, acid-base properties, and buffers.
- Describe the structure and acid-base properties of amino acids.
- Describe the structure of peptides and proteins, and how their structure relates to function.
- Explain how protein sequence is determined.
- Describe what allosteric proteins are, and their importance.
- Describe the structure, function, and behaviour of hemoglobin and myoglobin.
- Apply the principles of enzyme kinetics to describe quantitatively the activity and behaviour of enzymes.
- Explain basic bioenergetic principles as they relate to metabolism in the cell.
- Describe the structure and function of carbohydrates and lipids.
- Explain in detail the processes of glycolysis, Krebs cycle, electron transport and ATP synthesis.
- Describe the process of gluconeogenesis.
- Describe glycogen synthesis and glycogenolysis.
- Discuss the role of hormones in the regulation of cellular metabolism.
- Describe lipid metabolism.
- Describe nitrogen metabolism.
- Discuss how catabolic and anabolic pathways integrate in human metabolism.
