  • What is a phosphorylation cascade?

    A phosphorylation cascade is a series of protein kinases that amplify a signal through successive phosphorylation events.

  • What role do kinases play in a phosphorylation cascade?

    Kinases phosphorylate and activate other kinases, leading to successive phosphorylation events that amplify the signal.

  • What happens when a signaling molecule binds to a receptor in a phosphorylation cascade?

    The receptor undergoes a conformational change, leading to the phosphorylation and activation of a kinase enzyme.

  • How does a phosphorylation cascade lead to a cellular response?

    Successive phosphorylation events amplify the signal, ultimately leading to a cellular response.
