Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is the greatest advantage of having multiple steps in a transduction pathway?
A
Having multiple steps in a pathway requires the least amount of ATP.
B
Having multiple steps provides for greater possible amplification of a signal.
C
Each individual step can remove excess phosphate groups from the cytoplasm.
D
Each step can be activated by several G proteins simultaneously.
Explanation: 

Detailed explanation-1: -The correct answer is a having multiple amplification steps provides for greater possible amplification of a signal.

Detailed explanation-2: -Signal transduction usually involves multiple steps, called a signal cascade. Multi-step pathways (signaling cascades) can amplify a signal; even just a few molecules can cause a large cell response. Advantage: multi-step pathways can provide for more ways to coordinate and regulate the response.

Detailed explanation-3: -Multistep pathways allows a small number of extracellular signaling molecules to be amplified to produce a large cellular response and also provide opportunity for regulation and coordination.

Detailed explanation-4: -Which of the following is the greatest advantage of having multiple steps in a transduction pathway? Having multiple steps provides for greater possible amplification of a signal.

Detailed explanation-5: -Signal transduction pathways play a crucial role in controlling the molecular processes that underlie living things, including metabolism, immunological responses, cell development, differentiation, and proliferation, as well as various forms of cell communication.
