Chapter 1. The Cell as a Unit of Health and Disease
k k k k k k k k k k




1 The nucleus
k , which is essential for function and
k k k k k k k



survival of the cell.
k k k k




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




B) contains the genetic code k k k




C) transforms cellular energy k k




D) initiates aerobic metabolism k k




2 Although energy is not made in mitochondria, they are known
k k k k k k k k k



as the power plants of the cell because they:
k k k k k k k k k




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




B) utilize glycolysis for oxidative energy.
k k k k




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




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




3 Although the basic structure of the cell plasma membrane is
k k k k k k k k k



formed by a lipid bilayer, most of the specific membrane
k k k k k k k k k k



functions are carried out by:
k k k k k




A) bound and transmembrane proteins. k k k




B) complex, long carbohydrate chains. k k k




C) surface antigens and hormone receptors. k k k k




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




4 To effectively relay signals, cell-to-cell communication
k k k k k



utilizes chemical messenger systems that:
k k k k k




A) displace surface receptor proteins. k k k




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




C) bind to contractile microfilaments.
k k k




D) release secretions into extracellular fluid.
k k k k

,5 Aerobic metabolism, also known as oxidative metabolism,
k k k k k k



provides energy by:
k k k




A) removing the phosphate bonds from ATP. k k k k k




B) combining hydrogen and oxygen to form water. k k k k k k




C) activating pyruvate stored in the cytoplasm.k k k k k




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




6 Exocytosis, the reverse of endocytosis, is important in
k k k k k k k



into the extracellular fluid.
k k k k




A) Engulfing and ingesting fluid and proteins for k k k k k k k



transport
k




B) Killing, degrading, and dissolving harmful
k k k k



microorganisms
k




C) Removing cellular debris and releasing k k k k k



synthesized substances
k k




D) Destruction of particles by lysosomal enzymes k k k k k



for secretion
k k




7 The process responsible for generating and conducting
k k k k k k



membrane potentials is:
k k k




A) diffusion of current-carrying ions. k k k




B) millivoltage of electrical potential. k k k




C) polarization of charged particles. k k k




D) ion channel neurotransmission.

8 Epithelial tissues are classified according to the shape of the
k k k k k k k k k



cells and the number of layers. Which of the following is a
k k k k k k k k k k k k



correctly matched description and type of epithelial tissue?
k k k k k k k k




A) Simple epithelium: cells in contact with
k k k k k k



intercellular matrix; some do not extend to
k k k k k k k k



surface
k

, B) Stratified epithelium: single layer of cells; all
k k k k k k



cells rest on basement membrane
k k k k k




C) Glandular epithelium: arise from surfacek k k k k



epithelia and underlying connective tissue
k k k k k




D) Pseudostratified epithelium: multiple layers of k k k k



cells; deepest layer rests on basement
k k k k k k



membrane
k




9 Connective tissue contains fibroblasts that are responsible for:
k k k k k k k




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




B) synthesis of collagen, elastin, and reticular
k k k k k



fibers.
k




C) forming tendons and the fascia that covers
k k k k k k k



muscles.
k




D) filling spaces between tissues to keep organs in
k k k k k k k



place.
k




10 Although all muscle tissue cells have some similarities,
k k k k k k k



smooth muscle (also known as involuntary muscle) differs
k k k k k k k k



by:
k




A) having dense bodies attached to actin filaments.
k k k k k kk




B) containing sarcomeres between Z lines and M k k k k k k



bands.
k




C) having rapid contractions and abundant cross-
k k k k k



striations.
k




D) contracting in response to increased k k k k



intracellular calcium.
