1. Which statement best describes the cellular function of metabolic
absorption? - Correct Answer: Cells can take in and use nutrients
2. Most of a cell's genetic information, including RNA and DNA, is contained in
the: - Correct Answer: Nucleolus
3. Which component of the cell produces hydrogen peroxide (H2O2) by using
oxygen to remove hydrogen atoms from specific substrates in an oxidative
reaction? - Correct Answer: Peroxisomes
4. Which cell component is capable of cellular autodigestion when it is
released during cell injury? - Correct Answer: Lysosomes
5. What is the sequence of steps in the development of a digestive enzyme by
the pancreas cells from the initial transcription to the release from the cell?
- Correct Answer: The enzyme is transcribed from DNA by RNA in the
nucleus, proceeds to the ribosome for synthesis, and is transported in a
secretory vesicle to the cell membrane.
,6. During which phase of the cell cycle is DNA synthesized? - Correct
Answer: S phase
7. What organic compound facilitates transportation across cell membranes by
acting as receptors, transport channels for electrolytes, and enzymes to
drive active pumps? - Correct Answer: Proteins
8. Understanding the various steps of proteolytic cascades, such as caspase-
mediated apoptosis and complement cascades, may be useful in designing
drug therapy for which human diseases? - Correct Answer:
Autoimmune and malignant disorders
9. Which structure prevents water-soluble molecules from entering cells
across the plasma membrane? - Correct Answer: Lipid Bilayer
10.The fluid mosaic model explains: - Correct Answer: How a cell
membrane functions
11.Which form of cell communication is used to communicate within the cell
itself and with other cells in direct physical contact? - Correct Answer:
Protein channel (gap junction)
12.Which mode of chemical signaling uses blood to transport communication
to cells some distance away? - Correct Answer: Hormonal
,13.Which mode of chemical signaling uses local chemical mediators that are
quickly taken up, destroyed, or immobilized? - Correct Answer:
Paracrine
14.Neurotransmitters affect the postsynaptic membrane by binding to: -
Correct Answer: Receptors
15.How do cells receive communication from the extracellular fluid
surrounding them? - Correct Answer: Chemical messengers such as
ligands
16.When a second message is necessary for extracellular communication to be
activated, it is provided by which one? - Correct Answer: Adenosine
monophosphate (AMP)
17.Under anaerobic conditions, what process provides energy for the cell? -
Correct Answer: Glycolysis
18.What is the mechanism by which the energy produced from carbohydrates,
proteins, and lipids is transferred to adenosine triphosphate (ATP)? -
Correct Answer: Oxidative phosphorylation
19.Passive transport is best described with which statement? - Correct
Answer: Being driven by osmosis, hydrostatic pressure, and diffusion
, 20.Active transport occurs across which type of membranes? - Correct
Answer: Membranes that have receptors that are capable of binding with
the substances to be transported.
21.Which method of transport uses transmembrane proteins with receptors
with a high degree of specificity for the substance being transported? -
Correct Answer: Mediated
22.The movement of fluid across the arterial end of capillary membranes into
the interstitial fluid surrounding the capillary is an example of which fluid
movement process? - Correct Answer: Hydrostatic Pressure
23.Why is osmolality preferred over osmolarity as the measurement of osmotic
activity in the clinical assessment of individuals? - Correct Answer: More
of the weight of plasma is influenced by solutes, such as protein and
glucose, rather than by water
24.A patient who has diarrhea receives a 3% saline solution intravenously to
replace the sodium and chloride lost in the stool. What effect will this fluid
replacement have on cells? - Correct Answer: Shrink
25.The transport of glucose from the blood to the cell is accomplished by
which process? - Correct Answer: Passive-mediated transport
(facilitated diffusion)
26.Potassium and sodium are transported across plasma membranes by -
Correct Answer: Adenosine triphosphate enzyme
