Week 4 Quiz
Question 1 of 10
How does ATP differ from a RNA nucleotide?
o
ATP and RNA nucleotide and identical
o
ATP has deoxyribose instead of ribose
o
ATP has 3 phosphate group
o
ATP lacks an adenine
o
ATP has a 3C sugar
Question 2 of 10
What examples describe the second law of
thermodynamics? Select all that apply.
o
. A penny will fall when you pick it up
and let it drop.
o
B. A frying pan is on a hot stove. When
removed it will cool.
o
C. Ice cubes will melt in a warm room.
o
D. Donuts nutrients are used to help you
exercise.
Question 3 of 10
Since metabolism involves the synthesis and breakdown
of non-protein cell components like mono- and polysaccharides, lipids, and ATP,
there is not much role for gene mutations to influence the process.
o
True
o
False
Question 4 of 10
After many years of difficult research, your company
invented a drug that increases the enzyme rate for the synthesis of an
important metabolite. Patients with mutations in the enzyme lack the metabolite
and have devastating symptoms. Your team is thrilled to have a drug that speeds
up the enzymatic rate.
At your celebration, the new intern pipes up: “You
guys didn’t have to do all that work after all! Instead of giving patients this
new drug, you could have just given them the metabolite directly.”
Your response?
o
Products of metabolic reactions are not
easily digestible, so it would pass through the patient undigested.
o
Each enzyme can catalyze multiple
reactions. It is not feasible to provide enough of the metabolite to each cell
directly.
o
She is correct – this is an example of how
pharmaceutical companies create expensive drugs when a cheap solution would
solve the problem.
o
It would have been much easier to give
patients a small pill once a week containing the product of the reaction. But
that compound was already patented by another company.
Question 5 of 10
Glycerol and fatty acids can combine to make
triglycerides. This represents a(n)
o
degredation reaction
o
catabolic reaction
o
anabolic reaction
o
hydrolysis reaction
o
aerobic reaction
Question 6 of 10
o
There is not much energy in the glycosidic
bonds of cellulose, but at least there is a lot of it.
o
There is not much energy in the peptide
bonds of cellulose, but at least it is very easy to break down
o
The breakdown of cellulose into fructose
is an endergonic reaction, but an enzyme can reverse the equilibrium.
o
Cellulose is very difficult to break down
into glucose, but it contains a lot of energy.
Question 7 of 10
Making popsicles _____________the entropy of the
system.
o
increases
o
decreases
o
does not effect
Question 8 of 10
Neostigmine is a drug used to treat the disease

preventing the breakdown of acetylcholine. This drug is a(n)

noncompetitive inhibitor
o
allosteric inhibitor
o
allosteric activator
o
competitive inhibitor
Question 9 of 10
