A Brief Overview of Cellular Communication
How do cells communicate with each other?
🦜 Overview of Cellular Communication
Cells communicate with each other by sending and receiving signals. These signals can come from other cells or from the environment, and they allow cells to respond appropriately to changes in their surroundings. In this post, we will explore the components of cellular signaling, the processes involved, and the importance of understanding cellular communication.
📶 Components of Cellular Signaling
There are four main components necessary for cellular signaling: a signaling cell, a signaling molecule, a receptor protein, and a responding cell.
1. Signaling Cell
The signaling cell is responsible for releasing signaling molecules in response to changes in its environment or other signaling cues from other cells.
2. Signaling Molecule
Signaling molecules, also known as ligands, are molecules that bind to receptors on other cells in order to initiate a physiological response. The signaling molecule, or ligand, can be a protein, amino acid, ion, gas, or lipid, and the polarity of these molecules affects whether their…
