Chapter 1Introduction to Pathophysiology
gg gg gg




1. The nucleus gg , which is essential for function and survival of the cell.
gg gg gg gg gg gg gg gg gg gg




A) is the site of protein synthesis
gg gg gg gg gg




B) contains the genetic code gg gg gg




C) transforms cellular energy gg gg




D) initiates aerobic metabolism gg gg




2. Although energy is not made in mitochondria, they are known as the power
gg gg gg gg gg gg gg gg g gg gg gg


plants of the cell because they:
gg gg gg gg gg gg




A) contain RNA for protein synthesis.
gg gg gg gg




B) utilize glycolysis foroxidative energy.
g gg gg




C) extract energy from organic compounds.
gg gg gg gg




D) store calcium bonds for muscle contractions.
gg gg gg gg gg




3. Although the basic structure of the cell plasma membrane is formed by a lipid
gg gg gg gg gg gg gg gg gg gg gg gg gg


bilayer, most of the specific membrane functions are carried out by:
gg gg gg gg gg gg gg gg gg gg gg




A) bound and transmembrane proteins.
gg gg gg




B) complex,long carbohydratechains. g gg




C) surface antigens and hormone receptors.
gg gg ss gg




D) a gating system of selective ion channels.
gg gg gg gg gg gg




4. To effectively relay signals, cell-to-cell communication utilizes chemical
gg gg gg gg gg gg gg


messenger systems that:
gg gg gg




A) displacesurface receptor proteins. gg gg




B) accumulate within cell gap junctions. gg gg gg gg




C) bindto contractile microfilaments.
g gg gg




D) release secretions intoextracellular fluid.
gg gg gg




5. Aerobic metabolism, also known as oxidative metabolism, provides energy by:
gg gg gg gg gg gg gg gg gg

,A) removing the phosphate bondsfromATP. gg gg gg g




B) combining hydrogen and oxygen to formwater. gg gg gg gg gg




C) activatingpyruvate stored in the cytoplasm. gg gg gg gg




D) breaking down glucose to form lactic acid.
gg gg gg gg gg gg




6. Exocytosis, the reverse of endocytosis, is important in
gg gg gg gg gg gg gg into the
ss




extracellular fluid.
gg gg




A) Engulfing and ingesting fluid and proteins for transport
gg gg gg gg gg gg gg




B) Killing, degrading, anddissolving harmfulmicroorganisms
ss gg gg




C) Removingcellulardebris and releasing synthesized substances g gg gg gg




D) Destruction ofparticles by lysosomal enzymes for secretion
gg gg gg gg gg gg




7. Theprocess responsible for generating and conducting membranepotentials is:
gg gg gg gg gg gg gg




A) diffusionofcurrent-carrying ions. gg




B) millivoltageofelectrical potential. gg




C) polarization ofcharged particles. gg gg




D) ion channel neurotransmission.

8. Epithelial tissues are classified according to the shape of the cells and
gg gg gg gg gg gg gg gg gg gg gg


the number of layers. Which of the following is a correctly matched
gg gg gg gg gg gg gg gg gg gg gg gg


description and type of epithelial tissue?
gg gg gg gg gg gg




A) Simple epithelium: cells in contact with intercellular matrix; some do not
gg gg gg gg gg gg gg gg gg gg


extend to surface
gg gg gg




B) Stratified epithelium: single layer ofcells; all cells rest on basement
gg gg gg gg gg gg gg gg gg


membrane
gg




C) Glandular epithelium: arise from surface epithelia and underlying
gg g gg gg gg gg gg


connective tissue
gg gg




D) Pseudostratified epithelium: multiple layers of cells; deepest layer rests on gg gg gg gg gg gg gg gg gg


basement membrane
gg gg




9. Connective tissue contains fibroblasts thatare responsible for:
gg gg gg gg gg gg




A) providing a fibrous framework for capillaries.
gg gg gg gg gg




B) synthesis ofcollagen, elastin, and reticular fibers.
gg gg gg gg gg

, C) forming tendons and the fascia that covers muscles.
gg gg gg gg gg gg gg




D) filling spaces between tissues to keep organs in place.
gg gg gg gg gg gg gg gg




10. Although all muscle tissue cells have some similarities, smooth muscle (also
gg gg gg gg gg gg gg gg gg gg


known as involuntary muscle) differs by:
gg gg gg gg gg gg




A) having dense bodies attached to actin filaments.
gg gg gg gg gg gg




B) containing sarcomeres between Z lines and M bands. gg gg gg gg gg gg gg




C) havingrapid contractions and abundant cross-striations. gg gg gg gg




D) contracting in responseto increased intracellular calcium.gg gg g gg gg gg




11. Which of the following aspects of the function of the nucleus is performed by
gg gg gg gg gg gg gg gg gg gg gg gg gg


ribosomal RNA (rRNA)?
gg gg gg




A) Copyingand carrying DNA instructions forprotein synthesis gg gg gg gg gg




B) Carrying amino acids to the site of protein synthesis
gg gg gg gg gg gg gg gg




C) Providing the sitewhereprotein synthesis occurs gg gg gg gg




D) Regulating and controllingprotein synthesis gg gg gg




12. Breakdown and removal of foreign substances and worn-out cell parts are
gg gg gg gg gg gg gg gg gg gg


performed by which of the following organelles?
gg gg gg gg gg gg gg




A) Lysosomes
B) Golgi apparatus gg




C) Ribosomes
D) Endoplasmic reticulum(ER) ss




13. Impairment in the function ofperoxisomes would result in:
gg gg gg gg gg gg gg




A) inadequatesites for protein synthesis. gg gg gg




B) an inability to transport cellular products across the cell membrane.
g gg gg gg gg gg gg gg gg




C) insufficient energy production within a cell. gg gg gg gg gg




D) accumulation offree radicals in the cytoplasm. gg gg gg gg gg




14. After several months of trying to conceive, a couple is undergoing
gg gg gg gg gg gg gg gg gg gg


fertility testing. Semen analysis indicates that the mans spermhave decreased
gg gg gg gg gg gg gg gg gg gg


motility, a finding that is thought to underlie the couples inability to
gg gg gg gg gg gg gg gg gg gg gg gg


become pregnant.
