Questions and Verified Answers | Pass
Guaranteed - A+ Graded
How are cells specialized? - ANSWER through the process of
differentiation or maturation
What are the eight specialized cellular functions? - ANSWER
movement, conductivity, metabolic absorption, secretion, excretion, respiration,
reproduction, and communication
What are the three general components of an eukaryotic cell? - ANSWER
the plasma membrane, the cytoplasm, and the intracellular organelles.
What causes the release of lysosomal enzemes? - ANSWER Cellular
injury causing cellular self-digestion
What is the location and function of the nucleus? - 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? - 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? - 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? - 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? - 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? - ANSWER involved in the production and
breakdown of hydrogen peroxide
Importance of proteins in disease - ANSWER The major workhorses of
the cell, if misfolded they can cause diseases
What are mitochondria responsible for? - ANSWER . Mitochondria
contain the metabolic machinery necessary for cellular energy metabolism (Makes
ATP).
What is the cytoskeleton? - 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? - ANSWER encloses the cell and, by
controlling the movement of substances across it, exerts a powerful influence on
metabolic pathways
What is signal transduction? - 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? - 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? - ANSWER on the plasma membrane,
enable the cell to interact with other cells and with extracellular substances
What means accomplish cell-to-cell adhesions? - ANSWER (1) the
extracellular membrane, (2) cell adhesion molecules in the cell's plasma
membrane, and (3) specialized cell junctions.
What makes up the extracellular matrix and what does it do? - ANSWER
(1) fibrous structural proteins (collagen and elastin), (2) adhesive glycoproteins,
and (3) proteoglycans and hyaluronic acid. The matrix helps regulate cell growth,
movement, and differentiation.
