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



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



B) contains the genetic code g g g



C) transforms cellular energy g g



D) initiates aerobic metabolism g g



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


plants of the cell because they:
g g g g g g



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



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



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



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



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


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



A) bound and transmembrane proteins.
g g g



B) complex, long carbohydrate chains. g g g



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



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



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


messenger systems that:
g g g



A) displace surface receptor proteins.
g g g



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



C) bind to contractile microfilaments.
g g g



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



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

,A) removing the phosphate bonds from ATP.
g g g g g



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



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



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



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


extracellular fluid.
g g



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



B) Killing, degrading, and dissolving harmful microorganisms
g g g g g



C) Removing cellular debris and releasing synthesized substances
g g g g g g



D) Destruction of particles by lysosomal enzymes for secretion
g g g g g g g



7. The process responsible for generating and conducting membrane potentials is:
g g g g g g g g g



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



B) millivoltage of electrical potential. g g g



C) polarization of charged particles. g g g



D) ion channel neurotransmission.

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


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


description and type of epithelial tissue?
g g g g g g



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


extend to surface
g g g



B) Stratified epithelium: single layer of cells; all cells rest on basement
g g g g g g g g g g


membrane
g



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


connective tissue
g g



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


basement membrane
g g



9. Connective tissue contains fibroblasts that are responsible for:
g g g g g g g



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



B) synthesis of collagen, elastin, and reticular fibers.
g g g g g g

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



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



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


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



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



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



C) having rapid contractions and abundant cross-striations.
g g g g g



D) contracting in response to increased intracellular calcium.
g g g g g g



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


ribosomal RNA (rRNA)?

g g g g g g



D) Regulating and controlling protein synthesis g g g g



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


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



A) Lysosomes
B) Golgi apparatus g



C) Ribosomes
D) Endoplasmic reticulum (ER) g g



13. Impairment in the function of peroxisomes would result in:
g g g g g g g g



A) inadequate sites for protein synthesis. g g g g



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



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



D) accumulation of free radicals in the cytoplasm. g g g g g g



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


testing. Semen analysis indicates that the mans sperm have decreased
g g g g g g g g g g


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


pregnant.
