Exams 1-4 Questions & Answers
large numbers of ribosomes are present in the cytoplasm of a cell, then the cell is
likelyto specialize in producing which of the following cellular molecules?
proteins
cellulose
nucleic acids
lipids
glycogen - CORRECT ANSWER-protiens
Which of the following organelles or structures is primarily involved in the synthesis of
lipids, bile, and drug detoxifications?
smooth endoplasmic reticulum
lysosome
rough endoplasmic reticulum
ribosome
contractile vacuole - CORRECT ANSWER-smooth endoplasmic recticulum
The Golgi apparatus has a polarity or sidedness to its structure and function. Which of
the following statements correctly describes this polarity?
transport vesicles fuse with one side of the Golgi and leave from the opposite side
,proteins in the Golgi may be sorted and modified as they move from one side of the
Golgi to the other
carbohydrates on proteins in the Golgi may be modified and/or sortedas they move from
one side of the Golgi to the other
secretory vesicles leave the Golgi on the "trans" side
All of the above correctly describe polar characteristics of the Golgi function. -
CORRECT ANSWER-All of the above correctly describe polar characteristics of the
Golgi function.
Hydrolytic enzymes must be segregated and packaged to prevent general destructionof
cellular components. Which of the following organelles contains such hydrolyticenzymes
in plant cells (think carefully)?
smooth endoplasmic reticulum
mitochondria
peroxisome
central vacuole
chloroplast - CORRECT ANSWER-central vacuole
One of the key innovations in the evolution of eukaryotes from a prokaryotic ancestoris
the endomembrane system. Which of the following gives rise to and/or is a signifcant
part of this endomembrane system?
outer nuclear membrane
mitochondria cristae membranes
,chloroplast membranes
plasma membrane
ribosomal membranes - CORRECT ANSWER-outer nuclear membrane
Motor proteins provide for molecular motion in cells by interacting with what types of
cellular structures?
cytoskeletal proteins and structures
sites of energy production in cellular respiration
cell membrane bound proteins
cellulose fibers in the plant cell wall
ribosomes - CORRECT ANSWER-cytoskeletal proteins and structures
which of the following statements about the cytoskeleton is a false statement?
movement of cilia and flagella is the result of motor proteins, as dynein, causing
microtubulesto move relative to each other
microtubules are mostly rigid and resist compression,whereas microfilaments provide
tension
chemicals that block the assembly of the cytoskeleton proteins could result in the loss of
cellular shape
the smooth endoplasmic reticulum is responsible for the assembly of the cytoskeleton.
, cytoskeletal function is made possible by the assembly and disassemblyof a globular
cellular proteins into complex linear aggregates - CORRECT ANSWER-the smooth
endoplasmic reticulum is responsible for the assembly of the cytoskeleton
plasmodesma in plant cells are most similar in function to which of the following
structures in animal cells?
desmosomes
tight junctions
the extracellular matrix
gap junctions
peroxisomes - CORRECT ANSWER-gap junctions
of the following what is the most likely pathway taken by a newly synthesized protein
that will be secreted by an animal cell?
ER → lysosomes → vesicles that fuse with nuclear membrane
ER → Golgi → nucleus
nucleus → ER →Golgi
ER → Golgi → vesicles that fuse with a cell's plasma membrane
Golgi → ER → lysosome - CORRECT ANSWER-ER > Golgi > vesicles that fuse with a
cell's plasma membrane
