QUESTIONS & ANSWERS

Chapter 1. The Cell as a Unit of Health and Disease
1 The nucleus , which is essential for function and
survival of the cell.
A) is the site of protein synthesis
B) contains the genetic code
C) transforms cellular energy
D) initiates aerobic metabolism
2 Although energy is not made in mitochondria, they are known
as the power plants of the cell because they:
A) contain RNA for protein synthesis.
B) utilize glycolysis for oxidative energy.
C) extract energy from organic compounds.
D) store calcium bonds for muscle contractions.
3 Although the basic structure of the cell plasma membrane is
formed by a lipid bilayer, most of the specific membrane
functions are carried out by:
A) bound and transmembrane proteins.
B) complex, long carbohydrate chains.
C) surface antigens and hormone receptors.
D) a gating system of selective ion channels.
4 To effectively relay signals, cell-to-cell communication
utilizes chemical messenger systems that:
A) displace surface receptor proteins.
B) accumulate within cell gap junctions.
C) bind to contractile microfilaments.
D) release secretions into extracellular fluid.

,5 Aerobic metabolism, also known as oxidative
