ADVANCED PATHOPHYSIOLOGY EXAM 1 QUESTIONS
COMPLETE WITH 100% VERIFIED CORRECT ANSWERS
\.What are the properties of a eukaryotic cell - ANSWERS-•
Well define nucleus.
• cells are larger and have more extensive intracellular anatomy and
organization than do prokaryotes.
• cells bind with deoxyribonucleic acid (DNA) and are involved in the
super coiling of DNA.
• cells have several chromosomes, protein production or synthesis
. it consists of three components: outer membrane called plasma
membrane, a fluid filling called cytoplasm, and the intra cellular organs
or organelles
\.How do cells communicate with each other and the
environment outside the cell - ANSWERS-Cells communicate by
using hundreds of signal molecules.
-they display plasma membrane-bound signaling molecules (receptor)
that affect the cell itself and other cells in direct physical contact
-they affect receptor proteins inside the target cell and the signal
molecule has to enter the cell to bind to them
,-they form protein channels (gap juctions) that directly coordinate the
activities of adjacent cells.
\.responsable for cellular respiration and energy production -
ANSWERS-mitocondria
\.they provide sites for cellular protein synthesis - ANSWERS-
ribosome
\.is the largest membrane bound organelle and is usually
found in the cell center, main function is cell division and
control of genetic information - ANSWERS-nucleus
\.is a small dense structure composed largely of RNA and
combine it with proteins - ANSWERS-nucleolus
\.are saclike structures that originate from the golgi complex
and contain digestive enzymes - ANSWERS-lysosomes
\.specializes in the synthesis and transport of the protein and
lipid components of most of the cells organelles - ANSWERS-
endoplasmic reticulum
, \.proteins from the endoplasmic reticulum are processed and
packaged into small membrane - ANSWERS-Golgi apparatus or
complex
\.membrane organelles that contain several oxidative
enzymes such as catalase and urate oxidase. those enzymes
use oxygen to remove hydrogen in an oxidative reaction that
produces hydrogen peroxide. - ANSWERS-peroxisomes
\.it is the gelatinous, semiliquid portion of the cytoplasm.
functions include: intermediary metabolism involving
enzymatic biochemical reactions; ribosomal protein synthesis
and storage of carbohydrates, fat and secretory vesicles -
ANSWERS-cytosol
\.maintains the cell's shape and internal organization -
ANSWERS-cytoskeleton
\.cells secrete local chemical mediators that are quickly
absorbed, destroyed and immobilized. - ANSWERS-paracrine
