, 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:
A) removing the phosphate bonds from ATP.
JN
B) combining hydrogen and oxygen to form water.
C) activating pyruvate stored in the cytoplasm.
U
D) breaking down glucose to form lactic acid.
6. Exocytosis, the reverse of endocytosis, is important in into the
R
extracellular fluid.
SE
A) Engulfing and ingesting fluid and proteins for transport
B) Killing, degrading, and dissolving harmful microorganisms
C) Removing cellular debris and releasing synthesized substances

, D) ion channel neurotransmission.
8. Epithelial tissues are classified according to the shape of the cells and the
number of layers. Which of the following is a correctly matched description
and type of epithelial tissue?
A) Simple epithelium: cells in contact with intercellular matrix; some do not
extend to surface
B) Stratified epithelium: single layer of cells; all cells rest on basement
membrane
C) Glandular epithelium: arise from surface epithelia and underlying
JN
connective tissue
D) Pseudostratified epithelium: multiple layers of cells; deepest layer rests on
U
basement membrane
9. Connective tissue contains fibroblasts that are responsible for:
R
A) providing a fibrous framework for capillaries.
SE
B) synthesis of collagen, elastin, and reticular fibers.
C) forming tendons and the fascia that covers muscles.
D) filling spaces between tissues to keep organs in place.
10. Although all muscle tissue cells have some similarities, smooth muscle (also
known as involuntary muscle) differs by:
A) having dense bodies attached to actin filaments.
B) containing sarcomeres between Z lines and M bands.
C) having rapid contractions and abundant cross-striations.
D) contracting in response to increased intracellular calcium.
