NURS 6501-Advanced Pathophysiology Quiz 1 | UPDATED
Questions with 100% Verified Answers
Walden University • NURS 6501
Q1: How are cells specialized?
A: through the process of differentiation or maturation
Q2: What are the eight specialized cellular functions?
A: movement, conductivity, metabolic absorption, secretion, excretion, respiration, reproduction, and communication
Q3: What are the three general components of an eukaryotic cell?
A: the plasma membrane, the cytoplasm, and the intracellular organelles.
Q4: What causes the release of lysosomal enzemes?
A: Cellular injury causing cellular self-digestion
Q5: What is the location and function of the nucleus?
A: 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.
Q6: What is Cytoplasm?
A: an aqueous solution (cytosol) that fills the space between the nucleus and the plasma membrane.
Q7: What is the endoplasmic reticulum and what does it specialize in?
A: 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
Q8: What is the Golgi complex and what does it do?
A: a network of smooth membranes and vesicles located near the nucleus. The Golgi complex is responsible for
processing and packaging proteins into secretory vesicles
, Q9: What are lysosomes and what do they do?
A: 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
Q10: What are peroxisomes?
A: involved in the production and breakdown of hydrogen peroxide
Q11: Importance of proteins in disease
A: The major workhorses of the cell, if misfolded they can cause diseases
Q12: What are mitochondria responsible for?
A: . Mitochondria contain the metabolic machinery necessary for cellular energy metabolism (Makes ATP).
Q13: What is the cytoskeleton?
A: the "bone and muscle" of the cell. The internal skeleton is composed of a network of protein filaments, including
microtubules and actin filaments (microfilaments).
Q14: What is the plasma membrane?
A: encloses the cell and, by controlling the movement of substances across it, exerts a powerful influence on metabolic
pathways
Q15: What is signal transduction?
A: The transfer of molecular signals from the exterior to the interior of a cell. If not done apoptosis occurs
Q16: What is protein regulation and what is it composed of?
A: 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.
Q17: What do protein receptors do?
A: on the plasma membrane, enable the cell to interact with other cells and with extracellular substances
