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 knownas
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 metabolism,provides energy by:

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 the extracellular fluid.
A) Engulfing and ingesting fluid and proteins fortransport
B) Killing, degrading, and dissolving harmfulmicroorganisms
C) Removing cellular debris and releasingsynthesized substances
D) Destruction of particles by lysosomal enzymesfor secretion
7 The process responsible for generating and conductingmembrane 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 thecells and the number of layers. Which of the
following is a correctly matched description and type of epithelial tissue?

B) Stratified epithelium: single layer of cells; allcells rest on basement membrane
C) Glandular epithelium: arise from surface epithelia and underlying
connective tissue
9 Connective tissue contains fibroblasts that are responsible for:
A) providing a fibrous framework for capillaries.
B) synthesis of collagen, elastin, and reticularfibers.
C) forming tendons and the fascia that coversmuscles.
D) filling spaces between tissues to keep organs inplace.
10 Although all muscle tissue cells have some similarities, smooth muscle (also known as involuntary
muscle) differsby:
A) having dense bodies attached to actinfilaments.
B) containing sarcomeres between Z lines and Mbands.
C) having rapid contractions and abundant cross-striations.
D) contracting in response to increasedintracellular calcium.
11 Which of the following aspects of the function of the nucleusis performed by ribosomal RNA (rRNA)?
