Worked Solution & Example Answer:Scientists are now turning to the study of the proteome (all of the proteins) of an organism rather than the study of single proteins - VCE - SSCE Biology - Question 1 - 2006 - Paper 1
Step 1
Briefly outline one reason why the emphasis is now on the study of all the proteins of an organism rather than on one protein at a time.
Answer
One reason for the shift in emphasis toward studying the entire proteome is the recognition that proteins often function cooperatively within complex biological systems. By examining all proteins simultaneously, researchers can gain insights into intricate interactions, regulatory mechanisms, and collective functions that would be missed if focusing on individual proteins.
Step 2
Explain why such a structure may be important in the function of a particular protein.
Answer
The pleated sheet structure is crucial for a protein's function because it influences the protein's overall shape and stability, which are essential for its biological role. This secondary structure can facilitate interactions with other molecules, thereby impacting processes such as enzyme activity, structural support, and signal transduction. Proper folding into such structures ensures that proteins achieve their functional conformations.
