Transduction

Explanation:

The first step in the process of sensation is the stimulation of the sensory receptor by an appropriate stimulus. This is followed by the transduction of the stimulus in which the sensory receptor converts the energy in the stimulus into a graded potential. The amplitude of graded potentials varies with the strength of the stimulus. When the strength of the stimulus is enough, an action potential is fired. For example, odorant molecules in the air stimulate olfactory receptors in the nose, which transduce the chemical energy of the molecules into electrical energy.

Transduction

Explanation:

Signal transduction commonly known as cell signaling is the transmission of the signals at molecular level from the exterior of the cell to the interior of the cell.

The signals from the exterior of the cell should be transferred to the interior in order to get an appropriate response.

This is done by the receptors of the cells. This process is very important for the growth of cells, response generation, effect of medicine et cetera.
