NSG 5003 UPDATED ACTUAL QUESTIONS
AND CORRECT ANSWERS
COMPREHENSIVE STUDY GUIDE
●● The eight specialized cellular functions are
Answer: movement, conductivity, metabolic absorption, secretion,
excretion, respiration, reproduction, communication
●● Eukaryotic cells
Answer: Contain a nucleus and other organelles that are bound by
membranes.
●● The eukaryotic cell consists of three general components
Answer: plasma membrane, cytoplasm, and intracellular organelles
●● Nucleus
Answer: A part of the cell containing DNA and RNA and responsible for
growth and reproduction
●● Vaults
Answer: cytoplasmic organelles that are carrying messengers of
ribonucleic acid (mRNA) from the nucleus to the ribosomal sites of
protein synthesis
, ●● plasma membrane (cell membrane)
Answer: It's function is to protect the cell and control what goes in and
out. It is not a solid structure. It is made of millions of smaller molecules
so it is flexible and porous (allows things to pass through it).
●● cellular receptors
Answer: protein molecules on the plasma membrane, in the cytoplasm,
or in the nucleus that can recognize and bind with specific smaller
molecules called ligands
●● Ligands
Answer: A molecule that binds specifically to a receptor site of another
molecule.
●● Cells are held together by three different means:
Answer: (1) the extracellular membrane, (2) cell adhesion molecules in
the cell's plasma membrane, and (3) specialized cell junctions.
●● Cells communicate in three main ways
Answer: (1) they form protein channels (gap junctions); (2)
they display receptors that affect intracellular processes or other cells in
direct physical
contact; and (3) they use receptor proteins inside the target cell.
