Cell Communication

Evolutionary Significance of Cellular Communication

Signal Transduction and Gene Expression

Questions to answer:

  1. Why do cells need to communicate?
  2. Explain what happens during the three phases of signal transduction.
  3. What is the purpose of second messengers?
  4. Diagram the epinephrine signaling pathway.  Diagram signal reception, transduction and response.
  5. Define each of the following phenomena, identify the organisms that they occur in, and explain how cellular signaling is used in each of them:
  1. Quorum Sensing
  2. Mating in Yeast
  3. Apoptosis
  1. Why do you think cellular signaling pathways and mechanisms are so universal among life’s domains?
