UKY BIO 315 Exam 2 Review 2026/2027 |
High-Yield Study Guide | Questions &
Answers
Endoplasmic Reticulum - correct answer-A system of membranes that is found in
a cell's cytoplasm and that assists in the production, processing, and transport of
proteins and in the production of lipids.
Golgi apparatus - correct answer-A system of membranes that modifies and
packages proteins and lipids for export by the cell
lysosomes - correct answer-cell organelle filled with enzymes needed to break
down certain materials in the cell
endosomes - correct answer-sorting of endocytosed material
allows for recycling of receptors
three mechanisms of protein transport - correct answer-nuclear pores, across
membranes, vesicles
Ran - correct answer-g protein that regulates the import through nuclear pores
, polyribosomes - correct answer-import proteins on the cell by binding to ER
membrane and translate the protein into the lumen
folding once in lumen
SRP - correct answer-signal recognition particle
g protein that helps import proteins to ER
like a matchmaker
GTP hydrolysis triggers translocator opening
COPII - correct answer-protein transport to golgi
COPI - correct answer-Golgi --> Golgi (retrograde)
cis-Golgi --> ER
clathrin vesicles - correct answer-all movement to lysosome
tethering proteins - correct answer-located on the membrane being targeted;
bind with Rab proteins to secure the vesicle on the surface
SNARE
phagosome - correct answer-Intracellular vesicle containing material taken up by
phagocytosis from outside the cell
autophagosome - correct answer-a vesicle formed around a worn-out organelle;
this vesicle then fuses with a lysosome which digests the organelle.
