Cell signaling pathways involve a series of molecular interactions that allow cells to respond to signals from their environment. These pathways typically involve receptors on the cell surface or inside the cell, which bind to specific ligands, triggering a cascade of downstream signaling events (Karp, 2017, p. 432). For example, the insulin signaling pathway involves the binding of insulin to its receptor on the cell surface, triggering a series of downstream signaling events that ultimately lead to the uptake of glucose by the cell.
