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

In addition to activating or inhibiting enzymes through allosteric regulation, what other means does a cell use to control enzymatic activity?
