There are many important roles for the dynamic nature of proteins in a cell.Which of the following is NOT likely to describe one such reason?
A)A protein's structure determines its function.
B)Other molecules could be needed to allow proteins to fold into their active (ordered)conformation.
C)Quaternary structures are usually very transient (occur for short periods of time).
D)Proteins are crucial for many cell functions.

Question

Quizplus · Accepted Answer

Quaternary structures are made up of multiple protein subunits that come together to form a larger complex, and while the assembly and disassembly of these structures may be dynamic, they are not typically described as transient since they can persist for extended periods of time. All of the other answer options describe important roles for the dynamic nature of proteins in cells. Proteins are key players in nearly all cellular processes, including metabolism, signaling, and gene expression, and their functions are almost entirely reliant on their specific three-dimensional structures. Proper folding of proteins can be assisted by other molecules such as chaperones or membranes, and many proteins undergo post-translational modifications that can affect their conformation and activity. Ultimately, the dynamic nature of proteins allows cells to respond to changing conditions and carry out a wide variety of specialized functions.
