BIL 150 TEST 3 QUESTIONS COMPLETE
WITH VERIFIED ANSWERS
\.which of the following organelles or structure is primarily involved in the
synthesis of lipids, bile, and drug detoxification? - ANSWERS-smooth endoplasmic
reticulum
\.the Golgi apparatus has a polarity or sidedness to its structure and function.
Which of the following statements correctly describes this polarity? - ANSWERS-all
of the above correctly describe polar characteristics of the Golgi function
\.hydrolytic enzymes must be segregated and packaged to prevent general
destruction of cellular components. Which of the following organelles contains
such hydrolytic enzymes in plant cells? - ANSWERS-central vacuole
\.one of the key innovations in the evolution of eukaryotes from a prokaryotic
ancestor is the endomembrane system. Which of the following gives rise to
and/or is a significant part of this endomembrane system? - ANSWERS-outer
nuclear membrane
\.motor proteins provide for molecular motion in cells by interacting with what
types of cellular structures? - ANSWERS-cytoskeletal proteins and structures
, \.which of the following statements about the cytoskeleton is a false statement? -
ANSWERS-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? - ANSWERS-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? - ANSWERS-ER > Golgi > vesicles
that fuse with a cell's plasma membrane
\.which of the following processes would likely include all other processes? -
ANSWERS-passive transport
\.which of the following factors would most likely lead to increase membrane
fluidity? - ANSWERS-a greater proportion of unsaturated phospholipids
\.you are working on a team that is designing a new drug. In order for this drug to
work, it must enter the cytoplasm of specific target cells. Which of the following
would be a factor that might best determine whether your molecule could
selectively enter into these target cells? - ANSWERS-a high hydrophobicity of the
drug molecule
\.a patient has had a serious accident and lost a lot of blood. In an attempt to
replenish body fluids, an equal volume of distilled water to the amount of blood
loss is transferred directly into one of her veins. What will be the most probable? -
ANSWERS-the patient's red blood cells will swell because the blood fluid has
become hypotonic compared to the cells
