1 The nucleus gv



, which is essential for function and su
gv gv gv gv gv gv gv



rvival of the cell. gv gv gv



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




B) contains the genetic code gv gv gv




C) transforms cellular energy gv gv




D) initiates aerobic metabolism gv gv




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



the power plants of the cell because they:
gv gv gv gv gv gv gv gv




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




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




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




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




3 Although the basic structure of the cell plasma membrane is for
gv gv gv gv gv gv gv gv gv gv



med by a lipid bilayer, most of the specific membrane function
gv gv gv gv gv gv gv gv gv gv



s are carried out by:
gv gv gv gv




A) bound and transmembrane proteins. gv gv gv




B) complex, long carbohydrate chains. gv gv gv




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




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




4 To effectively relay signals, cell-to-
gv gv gv gv



cell communication utilizes chemical messenger systems that:
gv gv gv gv gv gv




A) displace surface receptor proteins. gv gv gv

,B) accumulate within cell gap junctions. gv gv gv gv




C) bind to contractile microfilaments.
gv gv gv




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




5 Aerobic metabolism, also known as oxidative metabolism, pr
gv gv gv gv gv gv gv



ovides energy by:
gv gv




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




B) combining hydrogen and oxygen to form water gv gv gv gv gv gv



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




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




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



into the extracellular fluid. gv gv gv




A) Engulfing and ingesting fluid and proteins for trans gv gv gv gv gv gv gv



port
B) Killing, degrading, and dissolving harmful microorg
gv gv gv gv gv



anisms
C) Removing cellular debris and releasing synthesized gv gv gv gv gv



substances
gv




D) Destruction of particles by lysosomal enzymes fo gv gv gv gv gv gv



r secretion
gv




7 The process responsible for generating and conducting mem
gv gv gv gv gv gv gv



brane potentials is:
gv gv




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




B) millivoltage of electrical potential. gv gv gv




C) polarization of charged particles. gv gv gv




D) ion channel neurotransmission.

8 Epithelial tissues are classified according to the shape of the cel
gv gv gv gv gv gv gv gv gv gv



ls and the number of layers. Which of the following is a correct
gv gv gv gv gv gv gv gv gv gv gv gv



ly matched description and type of epithelial tissue?
gv gv gv gv gv gv gv

, A) Simple epithelium: cells in contact with intercell
gv gv gv gv gv gv



ular matrix; some do not extend to surface
gv gv gv gv gv gv gv




B) Stratified epithelium: single layer of cells; all ce
gv gv gv gv gv gv gv



lls rest on basement membrane
gv gv gv gv




C) Glandular epithelium: arise from surface epith gv gv gv gv gv



elia and underlying connective tissue
gv gv gv gv




D) Pseudostratified epithelium: multiple layers of c gv gv gv gv gv



ells; deepest layer rests on basement membran

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




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




B) synthesis of collagen, elastin, and reticular fiber
gv gv gv gv gv gv



s.
C) forming tendons and the fascia that covers muscles.
gv gv gv gv gv gv gv




D) filling spaces between tissues to keep organs in pla

ce.
10 Although all muscle tissue cells have some similarities, smooth
gv gv gv gv gv gv gv gv g



muscle (also known as involuntary muscle) differs by:
v gv gv gv gv gv gv gv




A) having dense bodies attached to actin filaments
gv gv gv gv gv gv



.
B) containing sarcomeres between Z lines and M bangv gv gv gv gv gv gv



ds.
C) having rapid contractions and abundant cross-
gv gv gv gv gv



striations.

D) contracting in response to increased intracellula gv gv gv gv gv



r calcium.
