The correct answer is - e. many different molecules form a signaling cascade.
Explanation:
Signal transduction is the number of events that take place inside the body of a human from the external atmosphere to transmitting a chemical or physical signal through a number of molecular events of signaling cascade.
The transmission of the particular chemical or physical signal is caused a sequence of phosphorylation events inside the cell it involves specific protein receptors and different types of molecules.
Energy convention: Convection is the motion of a fluid driven by temperature differences across that fluid. When a fluid is heated, the region in closest contact with the heat source becomes less dense due to increased kinetic energy in the particles. Convection is one of the fundamental ways that heat is transferred
