Which of the following is the best explanation for the fact that most transduction pathways have multiple steps?
A) Most of the steps were already in place because they are steps in other pathways.
B) Multiple steps in a pathway require the least amount of ATP.
C) Multiple steps provide for greater possible amplification of a signal.
D) Each individual step can remove excess phosphate groups from the cytoplasm.
E) Each step can be activated by several G proteins simultaneously.

Explanation:

1. Signal transduction also called as cell signaling, it is the transmission of molecular signals from outside side of the to its interior side.

2. Signals received by cells specifically and  must be transmitted effectively into the cell and, function correctly.  

3. The signal is first attach to the cell-surface receptors in a specific manner. And then with the help of various proteins, they reach to their final target and show their effect.

4. Most of the signal transduction pathways contain multiple steps, the reason is that multiple steps provide for greater possible amplification

of a signal.
