Ion channel signaling
RTK Singaling
What is the main benefit of cell signaling via direct physical contact and cell signaling over short distances (ex: nerve cell signaling)?
The cell is triggered to make insulin when a glucose molecule binds to a receptor on the surface of the beta-cell. This then activates a molecule inside the cell to activate the expression of the gene. This process in which cells communicate with each other is called ___________ pathway (two words).
