The general structural and functional differences between a nerve and smooth muscle cell within an individual are a result of
A)the proteome (proteins in a cell)that differ between muscle and nerve cells.
B)the genome (DNA in a cell)being different between muscle and nerve cells.
C)the relative amounts of certain proteins between muscle and nerve cells.
D)the proteome and the relative amounts of certain proteins that differ between muscle and nerve cells.
E)the genome and the relative amounts of certain proteins that differ between muscle and nerve cells.

Quizplus · Accepted Answer

The general structural and functional differences between a nerve and smooth muscle cell are not just a result of differences in the genome (DNA) or the proteome (proteins in the cell), but rather a combination of both. The proteome plays a crucial role in determining a cell's function, and the relative amounts of certain proteins between muscle and nerve cells will differ. Therefore, choice D, which takes both the proteome and the relative amounts of certain proteins into account, is the best choice.
