NURS 6501-Advanced Pathophysiology
Quiz 1 Exam Questions and Answers
Graded A+
How are cells specialized? - Correct answer-through the process of differentiation
or maturation
What are the eight specialized cellular functions? - Correct answer-movement,
conductivity, metabolic absorption, secretion, excretion, respiration, reproduction,
and communication
What are the three general components of an eukaryotic cell? - Correct answer-the
plasma membrane, the cytoplasm, and the intracellular organelles.
What causes the release of lysosomal enzemes? - Correct answer-Cellular injury
causing cellular self-digestion
What is the location and function of the nucleus? - Correct answer-the largest
membrane-bound organelle and is found usually in the cell's center. The chief
functions of the nucleus are cell division and control of genetic information.

,What is Cytoplasm? - Correct answer-an aqueous solution (cytosol) that fills the
space between the nucleus and the plasma membrane.
What is the endoplasmic reticulum and what does it specialize in? - Correct
answer-a network of tubular channels (cisternae) that extend throughout the outer
nuclear membrane. It specializes in the synthesis and transport of protein and lipid
components of most of the organelles
What is the Golgi complex and what does it do? - Correct answer-a network of
smooth membranes and vesicles located near the nucleus. The Golgi complex is
responsible for processing and packaging proteins into secretory vesicles
What are lysosomes and what do they do? - Correct answer-saclike structures that
originate from the Golgi complex and contain digestive enzymes. These enzymes
are responsible for digesting most cellular substances to their basic form, such as
amino acids, fatty acids, and carbohydrates
What are peroxisomes? - Correct answer-involved in the production and
breakdown of hydrogen peroxide
Importance of proteins in disease - Correct answer-The major workhorses of the
cell, if misfolded they can cause diseases

, What are mitochondria responsible for? - Correct answer-. Mitochondria contain
the metabolic machinery necessary for cellular energy metabolism (Makes ATP).
What is the cytoskeleton? - Correct answer-the "bone and muscle" of the cell. The
internal skeleton is composed of a network of protein filaments, including
microtubules and actin filaments (microfilaments).
What is the plasma membrane? - Correct answer-encloses the cell and, by
controlling the movement of substances across it, exerts a powerful influence on
metabolic pathways
What is signal transduction? - Correct answer-The transfer of molecular signals
from the exterior to the interior of a cell. If not done apoptosis occurs
What is protein regulation and what is it composed of? - Correct answer-protein
homeostasis and is defined by the proteostasis network. This network is composed
of ribosomes (makers), chaperones (helpers), and protein breakdown or proteolytic
systems. Malfunction of these systems is associated with disease.
What do protein receptors do? - Correct answer-on the plasma membrane, enable
the cell to interact with other cells and with extracellular substances
