Assignment Brief

Carry out an assignment entitled ”Macromolecules and their importance in key biological processes “.The assignment should be written in essay format with use of diagrams as appropriate. (2000-2500 word count).This assignment is in three parts:

Part A

Sickle cell anaemia is an inherited condition resulting from a base change in the genetic material, DNA.

i.          Describe how this base change results in a faulty protein molecule being made, that produces the condition (AC 1.1)

 

ii       Explain the inheritance pattern of the condition, using completed genetic diagrams

         (AC 2.1)

Part B

 Cell membranes have a structure which includes the following types of molecules: phospholipids; proteins; carbohydrates.

 For each type of molecule

i.   Outline its chemical structure. (AC 1.1)

ii. Describe its role in membrane functioning. (AC 1.1)

Part C

Aerobic respiration is the process by which cells obtain energy.

A series of enzyme catalysed reaction is required for this process.

i.   Explain the relationship between the structure of enzymes and their function. (AC 1.1)

ii.  Outline the key stages which are part of aerobic respiration, explaining how ATP is produced. (AC 3.1)

Details of  enzyme reactions in the biochemical pathways are not needed.

 You must

·            Accurately cite a range of  appropriate sources of information, listed at the end in Harvard format
