Refer to the figure below. The figure shows a signal transduction pathway in a cell.How does the number of molecules change as the signal is carried in this pathway?
A) The number of molecules gradually increases up to the point of cAMP production, then remains constant.
B) The number of molecules gradually increases up to the point of cAMP production, then increases exponentially.
C) The number of molecules maintains a constant of one-to-one signaling up to the point of cAMP production, then declines gradually.
D) The transfer of signal from one step to the next is a linear process throughout the entire pathway with one molecule signaling the next.
E) The transfer of signal from one step to the next is a random process with no specific trend in quantity of molecules produced at any given step.
