PATHOPHYSIOLOGY QUIZ 1 WITH
SOLUTIONS 2026
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.
, 2
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).
, 3
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
What means accomplish cell-to-cell adhesions? - correct-answer -(1) the
extracellular membrane, (2) cell adhesion molecules in the cell's plasma
membrane, and (3) specialized cell junctions.
