Describe the structure of a range of biologically important molecules and how structure enables function.
Assignment Title: Illustrated Essay
Proteins perform a wide range of essential functions in living things. This is due to their ability to fold into a specific shape, and, often, to their ability to alter their shape in a controlled and predetermined way. Protein structure is the key to their function.
You will write an illustrated essay chosen from the 3 titles listed below. Which ever title you choose you should show how protein structure is related to the functions you describe.
1. Describe the roles of proteins found in cell membranes.
2. Describe how enzymes are able to act as biological catalysts.
3. Using named examples explain how the structures of fibrous and globular proteins allow them to perform their required functions.
1. Clear description of the relationship between protein structure and function in the context of the chosen essay. (50%)
2. Choice of appropriate illustrations and their effective use to support the descriptions and/or explanations. (35%)
3. Identification of relevant texts referred to in the report using the Harvard referencing system outlined in the assignment handbook. (10%)
