Biology 1330: Functional Final Exam
With 100% Correct Answers.
When comparing liver cells and kidney cells within an organism, many differences can be
observed and documented. Which of the following is not a difference between liver cells and
kidney cells in the same animal?
Choose one:
A.
The different cells are generated during the animal's development.
B.
The different cells have different roles in the body.
C.
The different cells produce different proteins.
D.
The different cells express different genes.
E.
The different cells have different DNA. - Answer E. The different cells have different DNA
What do eukaryotic cells have that prokaryotes lack?
Choose one:
A.
nucleic acids
B.
a means of using chemical energy
C.
a cell wall
D.
a nucleus and membrane-bound organelles
E.
ribosomes - Answer D. a nucleus and membrane-bound organelles
Which of the following organelles are found in eukaryotes but not prokaryotes? Select all that
apply.
mitochondria
chloroplasts
, ribosomes
Nucleus
peroxisome
lysosome
Golgi apparatus
Endoplasmic reticulum - Answer All except Ribosomes
The hydrophobic "force" results from the fact that it is energetically unfavorable for
hydrophobic molecules to disrupt the hydrogen bonding network of water. This drives
hydrophobic amino acid side chains to interact with each other during protein folding, typically
in the interior of the protein. What would you expect to happen if a protein folded in a
hydrophobic environment such as the lipid bilayer of a cellular membrane?
Choose one:
A.
It is impossible to predict how a protein would behave in a hydrophobic environment.
B.
The protein would be expected to adopt the same conformation in a hydrophobic environment
as in an aqueous environment, since the noncovalent forces act the same in both.
C.
A protein would not fold in a hydrophobic environment and would remain a flexible chain.
D.
The polar and charged amino acid side chains would repel the hydrophobic molecules of the
environment, and would be forced into th - Answer D. The polar and charged amino acid side
chains would repel the hydrophobic molecules of the environment, and would be forced into
the interior of the protein, while the hydrophobic side chains would be exposed on the exterior.
sharing of electrons between atoms - Answer covalent bond
transfer of electrons from one atom to another - Answer ionic bond
