4.3 Signal Transduction - Review

This review will guide you through an adaptive, research-backed study session. As you answer questions, we will actively assess your current understanding of the material. Questions will continue to be drawn until you have demonstrated mastery of each learning objective.

Reviews are graded based on completion. You will receive full credit for achieving 100% mastery or answering all questions.

Learning objectives for this review:

  • Describe how different types of receptors (e.g., G-protein coupled receptors, receptor tyrosine kinases) initiate signaling cascades.
  • Discuss how molecules such as cAMP, IP3, and calcium ions amplify and propagate signals within the cell.
  • Explain how signal transduction can lead to various cellular responses, such as gene expression, enzyme activation, or changes in cell behavior.
