How insulin reach the target cell
WebAt the cellular level, insulin activates glucose and amino acids transport, lipid and glycogen metabolism, protein synthesis, and transcription of specific genes. Insulin-induced biological responses are mediated by a specific cell-surface receptor with tyrosine kinase activity. WebG proteins are a family of receptor proteins that are involved in transmitting signals from outside a cell to inside a cell. When a signaling molecule binds to a G protein, the G …
