QUESTION 6 Which of the following correctly describes a second messenger? O A protein, such as a G-protein, that is switched 'on' upon ligand binding to receptor. OAn enzyme that is activated upon ligand binding to receptor. An enzyme responsible for the cellular effects of a signal transduction pathway, like Protein Kinase A or Glycogen Phosphorylase. O None of the above QUESTION 7 As we learned in class, protein phosphatases catalyze removal of phosphate groups from proteins. How would the activity of a protein cell's response to growth factors? O Decrease glucose production O Increase glucose production O Decrease proliferation O Increase proliferation
