• Which chemical is called the second messenger?
• aDNA
• mRNA
• dGMP

,• cAMPANS: D

Feedback
A cAMP is the second messenger; aDNA is not. B cAMP is the
second messenger; mRNA is not. C cAMP is the second messenger; dGMP
is not.
D Correct. cAMP transmits information to the intracellular organelles when
activated by surface receptors on the plasma membrane.

• Which cellular component facilitates protein synthesis?
• Ribosomes
• Lysosomes
• Mitochondria
• Plasmalemma ANS: A

Feedback
• Correct. Ribosomes synthesize protein.
• Lysosomes facilitate the breakdown of intracellular and extracellular
substances. C Mitochondria generate energy.
D The plasmalemma provides a protective barrier and regulates the
transport ofsubstances to and from the cell.
