Answer:
The correct answer is the last statement.
Explanation:
Conveying a message from a membrane receptor to a molecule, which does a particular function within a cell takes place when a signaling molecule combines with a protein, which protrudes towards the external of a cell.
When the protein receptor needs to transmit a message into the cell, it is achieved by the process of signal transduction. In this method, a message from the extracellular matrix or the cell membrane is transmitted towards the nucleus of the cell. This is performed in order to convey information considering the extracellular matrix and the receptors.
