Chapter 1Introduction to Pathophysiology
z z z
1. The nucleus
z z , which is essential for function and survival of the cell.
z z z z z z z z z z
A) is the site of protein synthesis
z z z z z
B) contains the genetic code z z z
C) transforms cellular energy z z
D) initiates aerobic metabolism z z
2. Although energy is not made in mitochondria, they are known as the power pl
z z z z z z z z z z z z z
ants of the cell because they:
z z z z z
A) contain RNA for protein synthesis. z z z z
B) utilize glycolysis for oxidative energy.
z z z z
C) extract energy from organic compounds.
z z z z
D) store calcium bonds for muscle contractions.
z z z z z
3. Although the basic structure of the cell plasma membrane is formed by a lipid bil
z z z z z z z z z z z z z z
ayer, most of the specific membrane functions are carried out by: A) bound and trans
z z z z z z z z z z z z z z
membrane proteins. z
B) complex, long carbohydrate chains. z z z
C) surface antigens and hormone receptors.
z z z z
D) a gating system of selective ion channels.
z z z z z z
4. To effectively relay signals, cell-to-
z z z z
cell communication utilizes chemical messenger systems that:
z z z z z z
A) displace surface receptor proteins. z z z
B) accumulate within cell gap junctions. z z z z
C) bind to contractile microfilaments.
z z z
D) release secretions into extracellular fluid.
z z z z
5. Aerobic metabolism, also known as oxidative metabolism, provides energy by:
z z z z z z z z z
,A) removing the phosphate bonds from ATP. z z z z z
B) combining hydrogen and oxygen to form water. z z z z z z
C) activating pyruvate stored in the cytoplasm.z z z z z
D) breaking down glucose to form lactic acid.
z z z z z z
6. Exocytosis, the reverse of endocytosis, is important in
z z z z z z z z
into thez z
extracellular fluid. z
A) Engulfing and ingesting fluid and proteins for transport
z z z z z z z
B) Killing, degrading, and dissolving harmful microorganisms
z z z z z
C) Removing cellular debris and releasing synthesized substances
z z z z z z
D) Destruction of particles by lysosomal enzymes for secretion
z z z z z z z
7. The process responsible for generating and conducting membrane potentials is:
z z z z z z z z z
A) diffusion of current-carrying ions. z z z
B) millivoltage of electrical potential. z z z
C) polarization of charged particles. z z z
D) ion channel neurotransmission.

9. Connective tissue contains fibroblasts that are responsible for: A) p
z z z z z z z z z
roviding a fibrous framework for capillaries.
z z z z z
B) synthesis of collagen, elastin, and reticular fibers.
z z z z z z
, C) forming tendons and the fascia that covers muscles.
z z z z z z z
D) filling spaces between tissues to keep organs in place.
z z z z z z z z
10. Although all muscle tissue cells have some similarities, smooth muscle (also k
z z z z z z z z z z z
nown as involuntary muscle) differs by:
z z z z z
A) having dense bodies attached to actin filaments.
z z z z z z
B) containing sarcomeres between Z lines and M bands. z z z z z z z
C) having rapid contractions and abundant cross-striations.
z z z z z
D) contracting in response to increased intracellular calcium. z z z z z z
11. Which of the following aspects of the function of the nucleus is performed by rib
z z z z z z z z z z z z z z
osomal RNA (rRNA)? z z
A) Copying and carrying DNA instructions for protein synthesis
z z z z z z z
B) Carrying amino acids to the site of protein synthesis
z z z z z z z z
C) Providing the site where protein synthesis occurs z z z z z z
D) Regulating and controlling protein synthesis z z z z
12. Breakdown and removal of foreign substances and worn-
z z z z z z z
out cell parts are performed by which of the following organelles?
z z z z z z z z z z
A) Lysosomes
B) Golgi apparatus z
C) Ribosomes
D) Endoplasmic reticulum (ER) z z
13. Impairment in the function of peroxisomes would result in: A) i
z z z z z z z z z z
nadequate sites for protein synthesis.
z z z z
B) an inability to transport cellular products across the cell membrane.
z z z z z z z z z
C) insufficient energy production within a cell. z z z z z
D) accumulation of free radicals in the cytoplasm. z z z z z z

g. Semen analysis indicates that the mans sperm have decreased motility, a findin
z z z z z z z z z z z z
g that is thought to underlie the couples inability to become pregnant.
