AP BIOLOGY QUARTER 1 TEST
When you have a severe fever, what may be a grave consequence if this is not
controlled? - Correct Answers -change in the folding of enzymes
Where does glycolysis take place? - Correct Answers -cytosol
During glycolysis, when glucose is catabolized to pyruvate, most of the energy of
glucose is... - Correct Answers -retained in the pyruvate
A solution of starch at room temperature does not readily decompose to form a solution
of simple sugars because... - Correct Answers -the activation energy barrier for this
reaction cannot be surmounted
The molecule that functions as the reducing agent (electron donor) in a redox or
oxidation reaction... - Correct Answers -loses electrons and loses energy
Which metabolic pathway is common to both cellular respiration and fermentation? -
Correct Answers -glycolysis
In addition to ATP, what are the end products of glycolysis? - Correct Answers -NADH
and pyruvate
In a plant cell, where are the ATP synthase complexes located? - Correct Answers -The
inner mitochondrial membrane and the thylakoid membrane.
Describe enzyme cooperativity. - Correct Answers -A substrate molecule bound to an
active site affects the active site of several subunits.
What is the primary function of the Calvin Cycle? - Correct Answers -To synthesize
simple sugars from carbon dioxide.
When oxygen is released as a result of photosynthesis, it is a by-product of what? -
Correct Answers -The splitting of the water molecules.
An inhibitor of what could be used to block the release of calcium from the endoplasmic
reticulum? - Correct Answers -phospholipase C
The mechanism of action of many common medications involves interfering with the
normal pathways that cells use to respond to hormone signals. Describe a drug
interaction that directly interferes with a signal transduction pathway. - Correct Answers
, -A medication enters the target cell and inhibits an enzyme that normally synthesizes a
second messenger
Summarize the differences between DNA and RNA. - Correct Answers -DNA
nucleotides contain a different sugar than RNA nucleotides
The oxygen consumed during cellular respiration is involved in what process or event? -
Correct Answers -Accepting electrons at the end of the electron transport chain.
The mechanism in which the end product of a metabolic pathway inhibits an earlier step
in the pathway is known as... - Correct Answers -feedback inhibition
Where does the Calvin Cycle take place? - Correct Answers -Stroma of the chloroplast.
What term is used to describe the transfer of free energy from catabolic pathways to
anabolic pathways? - Correct Answers -energy coupling
The ATP made during glycolysis is generated by what? - Correct Answers -substrate-
level phosphorylation
CAM plants keep stomata closed in daytime, thus reducing water loss. They can do this
because they... - Correct Answers -fix CO2 into organic acids during the night
What is the cellular process of breaking down large molecules into smaller ones? -
Correct Answers -catabolism
How can one increase the rate of a chemical reaction? - Correct Answers -Add a
catalyst
In the absence of oxygen, yeast cells can obtain energy by fermentation, resulting in the
production of what? - Correct Answers -ATP, CO2, and ethanol (ethyl alcohol)
Starting with citrate, what combination of products would result from THREE turns of the
citric acid cycle? - Correct Answers -3 ATP, 6 CO2, 9 NADH, and 3 FADH2
During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a
Δ G of -20 kcal/mol. If you double the amount of enzyme in the reaction, what will be the
Δ G for the new reaction? - Correct Answers --20 kcal/mol
Which process in the eukaryotic cells will proceed normally whether oxygen is present
or absent? - Correct Answers -glycolysis
In chemiosmotic phosphorylation, what is the most direct source of energy that is used
to convert ADP +P to ATP? - Correct Answers -Energy released from movement of
protons through ATP synthase
