Chapter 1Introduction to Pathophysiology
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
powerplants 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 lipidbilayer, 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 chemicalmessenger 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 metabolism, provides energy by
:
,A) removing the phosphate bonds from ATP.
B) combining hydrogen and oxygen to form water.
C) activating pyruvate stored in the cytoplasm.
D) breaking down glucose to form lactic acid.
6. Exocytosis, the reverse of endocytosis, is important in
into theextracellular fluid.
A) Engulfing and ingesting fluid and proteins for transport
B) Killing, degrading, and dissolving harmful microorganisms
C) Removing cellular debris and releasing synthesized substances
D) Destruction of particles by lysosomal enzymes for secretion
7. The process responsible for generating and conducting membrane potentials is
:
A) diffusion of current-carrying ions.
B) millivoltage of electrical potential.
C) polarization of charged particles.
D) ion channel neurotransmission.
8. Epithelial tissues are classified according to the shape of the cells an
d the number of layers. Which of the following is a correctly matche
d descriptionand type of epithelial tissue?
A) Simple epithelium: cells in contact with intercellular matrix; some d
o notextend to surface
B) Stratified epithelium: single layer of cells; all cells rest on bas
ementmembrane
C) Glandular epithelium: arise from surface epithelia and underl
yingconnective tissue
D) Pseudostratified epithelium: multiple layers of cells; deepest layer rest
s onbasement membrane
9. Connective tissue contains fibroblasts that are responsible for:
A) providing a fibrous framework for capillaries.
B) synthesis of collagen, elastin, and reticular fibers.
, C) forming tendons and the fascia that covers muscles.
D) filling spaces between tissues to keep organs in place.
10. Although all muscle tissue cells have some similarities, smooth muscle
(alsoknown as involuntary muscle) differs by:
A) having dense bodies attached to actin filaments.
B) containing sarcomeres between Z lines and M bands.
C) having rapid contractions and abundant cross-striations.
D) contracting in response to increased intracellular calcium.
11. Which of the following aspects of the function of the nucleus is perfor
med byribosomal RNA (rRNA)?
A) Copyingxandxcarrying1xDNAxinstructionsxforxproteinxsynthesis
B) Carrying amino acids to the site of protein synthesis
C) Providing the site where protein synthesis occurs
D) Regulating and controlling protein synthesis
12. Breakdown and removal of foreign substances and worn-
out cell parts areperformed by which of the following organelles?
A) Lysosomes
B) Golgi apparatus
C) Ribosomes
D) Endoplasmic reticulum (ER)
13. Impairment in the function of peroxisomes would result in:
A) inadequate sites for protein synthesis.
B) an inability to transport cellular products across the cell membrane.
C) insufficient energy production within a cell.
D) accumulation of free radicals in the cytoplasm.
14. After several months of trying to conceive, a couple is undergoing ferti
lity testing. Semen analysis indicates that the mans sperm have decreased
motility,a finding that is thought to underlie the couples inability to bec
ome pregnant.
