PATHOPHYSIOLOGY ELABORATED
QUESTIONS WITH ANSWERS
Identiy the 3 major parts of a cell - CORRECT ANSWER-
plasma membrane, cytoplasm, and nucleus
what is the function of the plasma membrane.? - CORRECT
ANSWER-major structural feture is the phospholipid bilayer,
also contains recptors and pores , allow for material passage
and ingegrity of the cells
what is the function of the cytoplasm? - CORRECT ANSWER-
jelly-like substance which differs from cell type . Cellular
functions are performed in cytoplasm by organelles
what is the function of the nucleus? - CORRECT ANSWER-
absolutely necessary for the survival of the cell , also contains
genetic information
what is the function of the mitochondria? - CORRECT
ANSWER-extracts energy in the chemical bonds which
involves a series of chemical changes that relase the energy in
small easily handled amounts which is released, captured and
stored as ATP
what is the function of the ribosomes? - CORRECT ANSWER-
in protein synthisis they are the site of messenger
RNA=ribonucleic acid, attachment and amino acid assembly in
the sequence ordered by the genetic code carried by the RNA
they ar snall rounded masses that are interconnected to
cristernae.
, what is the function of the smooth ER? - CORRECT ANSWER-
when the long parallel arrays of flattened membranes called
cristernae are normally present in the cytoplasm
what is the function of the rough ER? - CORRECT ANSWER-
when the presence of ribosomes in the cytoplasm which are
interconnected to the cristeranae
what is the function of the golgi? - CORRECT ANSWER-small
peices of GER membrane containing newly synthesized
protein, pinch off from the GER and merge with the membrane
of the golgi complex, storesit until it is needed, often
carbohydrate or lipid is added to the stred protein to form a fully
functional lproduct for secretion to pass to th cells exterior,
vesicles lseperate from the golgi and move to the plasma
membrane, merge with it, passing the secretion to the exterior
where it may function locally or at some distant site to which a
duct or the blood delivers it.
what is the function of lyosomes - CORRECT ANSWER-freely
distributed in the cytoplasm and consist of a membrane vesicle
containing differnt enzymes which are capable of degrading or
breaking down proteins and carbs, for this reason lysosome
membranes must have chemincal properties that can resist the
activities of the enzymes that they contain , without this
resistance the enzymes would escape and destroy the cell of
which tey are a part of.
what is the function of cytoskeleton? - CORRECT ANSWER-it
contributes to the cell including support and organization of the
cells organelles and movement of materials within the cell b/c
the cytoskeleton is attached to the plasma membrane, it also
plays a role in maintaining cell structure and linking adajacent
cells
what are 3 major causes of cell injury? - CORRECT ANSWER-
deficiency, intoxications, and trauma
