BIO 111 PRACTICE EXAM TEST QUESTIONS WITH ACCURATE SOLUTIONS (GRADED A+)
What do mitochondria and chloroplasts have in common?
found in almost all plant cells,
evolution from endosymbiotic events
Which of the following is an example of potential rather than kinetic energy?
molecule of glucose
cells (e.g. bacteria) are ingested for food by other cells (e.g. an amoeba) by which of the
following?
Phagocytosis
which of the following is NOT considered part of the cell's endomembrane system?
mitochondria
Last week, biologists in Tel Aviv released a ground breaking discovery. There were the first
group to find a multicellular organism that _?
completely lacks a mitochondrial genome
Which of the following statements describes the second law of thermodynamics?
The entropy of the universe never decreases
,Which of the following is an example of cooperativity?
A molecule binding at one unit of a tetramer, allowing faster binding at each of the other
three
What is produced when animals undergo fermentation?
lactic acid
What is the name of letter D? (enzymatic reaction, pointing to two molecules produced)
products
HIV is the virus that causes AIDS. In the mid-1990s, researchers discovered an enzyme in
HIV called protease. Once the enzyme's structure was known, researchers began looking
for drugs that would fit into the active site and block it. If this strategy for stopping HIV
infections were successful, it would be an example of what phenomenon?
competitive inhibition
Your patient was involved in a serious accident and lost a large quantity of blood. In an
attempt to replenish body fluids, your rookie nurse adds distilled water (equal to the
volume of blood lost) to the patient's blood directly via one of his veins, without consulting
you. What will be the most probable result of this transfusion?
The patient's red blood cells will swell and possibly burst as the water moves into the cells.
, Which organelle is responsible for containing degradative enzymes enclosed in a
membrane that help remove water products?
lysosomes
Which of the following is FALSE about the relationship between canabolism and
anabolism?
The ATP generated from anabolic reactions drives catabolic reactions
In the absence of oxygen, suppose a single yeast cell undergoes fermentation and uses 56
molecules of glucose. How many molecules of ATP will be generated?
112
Dopamine is a neurotransmitter that functions as part of the reward-motivation behavior
pathway. Which of the following is NOT true about this chemical?
It is only found in the brain.
Household bleach has a pH of 12. How many OH- ions and H+ ions does it have?
OH: 10^-2 H+: 10^-12
The construction of macromolecules requires a series of _ reactions that form _ bonds
between monomers.
dehydration; covalent
