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
$vf $vf $vf $vf $vf


metabolism, provides energy by:
$vf $vf $vf $vf



A) removing the phosphate bonds from ATP. $vf $vf $vf $vf $vf



B) combining hydrogen and oxygen to form $vf $vf $vf $vf $vf


water.
$vf



C) activating pyruvate stored in the cytoplasm. $vf $vf $vf $vf $vf



D) breaking down glucose to form lactic acid.
$vf $vf $vf $vf $vf $vf



6 Exocytosis, the reverse of endocytosis, is important in
$vf $vf $vf $vf $vf $vf $vf


into the extracellular fluid.
$vf $vf $vf



A) Engulfing and ingesting fluid and proteins for
$vf $vf $vf $vf $vf $vf


transport
$vf



B) Killing, degrading, and dissolving harmful
$vf $vf $vf $vf


microorganisms
$vf



C) Removing cellular debris and releasing $vf $vf $vf $vf


synthesized substances
$vf $vf



D) Destruction of particles by lysosomal $vf $vf $vf $vf


enzymes for secretion
$vf $vf $vf



7 The process responsible for generating and conducting
$vf $vf $vf $vf $vf $vf


membrane potentials is:
$vf $vf $vf



A) diffusion of current-carrying ions. $vf $vf $vf



B) millivoltage of electrical potential. $vf $vf $vf

8 Epithelial tissues are classified according to the shape of
$vf $vf $vf $vf $vf $vf $vf $vf


the cells and the number of layers. Which of the
$vf $vf $vf $vf $vf $vf $vf $vf $vf $vf


following is a correctly matched description and type of
$vf $vf $vf $vf $vf $vf $vf $vf $vf


epithelial tissue?
$vf $vf



A) Simple epithelium: cells in contact with $vf $vf $vf $vf $vf


intercellular matrix; some do not extend to
$vf $vf $vf $vf $vf $vf $vf


surface $vf

, B) Stratified epithelium: single layer of cells;
$vf $vf $vf $vf $vf


all cells rest on basement membrane
$vf $vf $vf $vf $vf $vf



C) Glandular epithelium: arise from surface $vf $vf $vf $vf


epithelia and underlying connective tissue
$vf $vf $vf $vf $vf



D) Pseudostratified epithelium: multiple layers $vf $vf $vf


of cells; deepest layer rests on basement
$vf $vf $vf $vf $vf $vf $vf


membrane
$vf



9 Connective tissue contains fibroblasts that are responsible for:
$vf $vf $vf $vf $vf $vf $vf



A) providing a fibrous framework for capillaries. $vf $vf $vf $vf $vf



B) synthesis of collagen, elastin, and reticular
$vf $vf $vf $vf $vf


fibers.
$vf



C) forming tendons and the fascia that covers
$vf $vf $vf $vf $vf $vf


muscles.
$vf



D) filling spaces between tissues to keep organs in
$vf $vf $vf $vf $vf $vf $vf


place.
$vf



10 Although all muscle tissue cells have some
$vf $vf $vf $vf $vf $vf


similarities, smooth muscle (also known as involuntary
$vf $vf $vf $vf $vf $vf $vf


muscle) differs by:
$vf $vf $vf



A) having dense bodies attached to actin $vf $vf $vf $vf $vf


filaments. $vf



B) containing sarcomeres between Z lines and M $vf $vf $vf $vf $vf $vf


bands.
$vf



C) having rapid contractions and abundant cross-
$vf $vf $vf $vf $vf


striations.
$vf



D) contracting in response to increased $vf $vf $vf $vf


intracellular calcium.
$vf $vf



11 Which of the following aspects of the function of the
$vf $vf $vf $vf $vf $vf $vf $vf $vf


nucleus is performed by ribosomal RNA (rRNA)?
$vf $vf $vf $vf $vf $vf $vf



A) Copying and carrying DNA instructions $vf $vf $vf $vf


for protein synthesis $vf $vf $vf
