Understand the components involved in cell communication. Cell communication typically involves a signal molecule, a receptor protein, and a response mechanism.
Signal molecules are often hormones or neurotransmitters that initiate the communication process by binding to receptor proteins.
Receptor proteins are located on the cell surface or inside the cell and are responsible for receiving the signal molecule.
The response mechanism is the series of events that occur within the cell after the receptor protein has received the signal molecule, leading to a specific cellular response.
Mitochondrial DNA is not involved in the cell communication process. It is the genetic material found in mitochondria, responsible for encoding proteins needed for mitochondrial function, not for cell signaling.
