Place the following cell signaling steps in the correct order. Question 12 options: Proteins within the target cell are activated. A ligand is released by a cell that is sending a signal. A cellular response (e.g. cell division) occurs. The receptor on the target cell is activated. The ligand binds to a receptor on a cell.

Put the steps of the process of signal transduction in the order they occur. 1 Protein Kinases are activated 2 Target proteins are phosphorylated 3 Second messenger molecules are released 4 A signal molecule (ligand) binds to a receptor 5 A conformational change in the signal receptor complex activates an enzyme 4, 5, 1, 3, 2 3, 1, 5, 2, 4 1, 2, 3, 4, 5 4, 5, 3, 1, 2
