Put the steps of the process of signal transduction in the order they occur. a conformational change in the signal-receptor complex activates an enzyme. protein kinases are activated. a signal molecule binds to a receptor. target proteins are phosphorylated. second messenger molecules are released.

Signal transduction can be defined as the process in which a physical or chemical signal is transmitted through a cell as a series of molecular events inform of protein phosphorylation are catalyzed by protein kinase and this ultimately result into a cellular response. However, the protein that is responsible for the detection of stimuli is commonly refers to as receptors or sensor.
