10. When a primary signal needs to be sent to most cells throughout a multicellular organism, the signal most suited for this is a neurotransmitter. 11. AG) AH) hormone. AI) dissolved gas. AJ) transcription factor. AK) translation elongation factor Answer: Explanation: Hydrophobic primary messengers usually cause molecular changes leading to modifications in metabolism. Examples of hydrophobic primary messengers are Explain what are their general chemical properties. AL) thyroxine (tyrosine-derived hormone) and insulin (a small peptide hormone) AM) the steroid hormones AN) tyrosine-derived epinephrin and norepinephrin AO) serotonin and melatonin (tryptophan-derived mammalian neurotransmitters) AP) auxins (tryptophan-derived plant hormones) Answer: Explanation: 12. Which statement regarding cell-surface receptors is correct? AQ) lon-channel-coupled receptors alter the membrane potential directly by changing the permeability of the plasma membrane. AR) G-protein-coupled receptors are polypeptides with seven transmembrane domains. AS) After binding their ligand, G-protein-coupled receptors interact with intracellular GTP-binding proteins, later initiating signal transduction events. AT) All of the above AU) None of the above Answer: Explanation: 13. Which of the following are secondary messengers? AV) Ca²+, GTP, CAMP AW) hormones AX) growth factors AY) neurotransmitters AZ) None of the above Answer: Explanation:
