- Relaying a message from a receptor protein to a molecule that performs a specific function within a cell is called ______. selective permeability signal transduction inhibition self-recognitionDuring cell signaling, binding of a ligand to the outside of a cell leads to: A. A signal being sent inside the cell B. The ligand being transported into the cell C. A and B D. None of the aboveThe 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).
- Identify which of the following statements is a lie? Select one: a. Protein kinase C can add a phosphate group in the hydroxyl groups of target proteins. b. PKC is involved in gene regulation. c.
