NURS 340 EXAM 1 NEWEST 2025 /NURS 340 HEALTH
ASSESSMENT EXAM 1 AND STUDY GUIDE NEWEST
2024 ACTUAL EXAM 200 QUESTIONS AND CORRECT
DETAILED ANSWERS (VERIFIED ANSWERS) |ALREADY
GRADED A+
Nucleus .....ANSWER.....contains the nucleolus, a small dense
structure composed largely of RNA, most of the cellular DNA,
and the DNA-binding proteins, the histones, that regulate its
activity
What 4 elements is DNA composed of? .....ANSWER.....1)
deoxyribose
phosphate molecule
2) pyrimidine bases
3) purine bases
,Page 2 of 67
4) hydrogen bonds (stabilize the helix through large numbers)
what are Ribosomes? .....ANSWER.....RNA-protein complexes
(nucleoproteins) that are synthesized in the nucleolus and
secreted into the cytoplasm through pores in the nuclear
envelope called nuclear pore complexes (NPCs)
What is the chief function of Ribosomes .....ANSWER.....Chief
function of ribosomes is to provide sites for cellular protein
synthesis
Golgi Complex .....ANSWER.....-network of flattened, smooth
membranes and vesicles frequently located near the nucleus of
the cell.
-Proteins from the ER are processed and packaged into small
membrane-bound sacs or vesicles called secretory vesicles.
- refining plant and directs traffic into the cell.
Lysosomes .....ANSWER.....maintain cellular health
,Page 3 of 67
- efficient removal of toxic cellular components
-if damaged, will release and cause AUTODIGESTION
-removal of useless organelles
- signals cellular adaptation
what do Peroxisomes contain? .....ANSWER.....hydrogen peroxide
and other oxygen reactive species
Mitochondria .....ANSWER.....- responsible for cellular respiration
and energy production.
-THINK ATP (energy) - ATP functions as the energy-transferring
molecule.
- urea and heme synthesis
How does a virus get into a cell? .....ANSWER.....-through trickery!
-attaches to the cell and release and enzyme to facilitate
entrance to the cell
, Page 4 of 67
-also by bacteria and parasites
Diffusion .....ANSWER.....passive
process by which molecules move from an area of high
concentration to an area of low concentration
facilitated diffusion .....ANSWER.....-needs help to enter the cell
- ex: insulin attaches to a receptor to let glucose in
Active transport .....ANSWER.....-movement of a solute molecule
from an area of low concentration to an area of high
concentration
- going against the gradient needs energy
What cells in our body cannot reproduce?
.....ANSWER.....neurons, heart cells, skeletal muscle cells, red
blood cells
-they do not reproduce or transform, but some can be created
by the body
