QUESTIONS AND ANSWERS,
DOWNLOAD TO SCORE GRADE A
A dehydration reaction _______ a polypeptide, whereas a
hydrolysis reaction ______ a polypeptide. ......ANSWER.....A
dehydration reaction builds a polypeptide, whereas a hydrolysis
reaction breaks a polypeptide.
During feedback inhibition, a molecule acts as an ____ for an
enzyme in order to________. ......ANSWER.....During feedback
inhibition, a molecule acts as an inhibitor for an enzyme in order
to prevent over production of a product.
Replacing a polar amino acid with a non-polar amino acid will
likely cause ________. ......ANSWER.....a neurodegenerative disease.
Characteristics of hemoglobin in the lung: ......ANSWER.....1.
Relaxed, planar state
,2|Page
2. Oxygenated - high affinity for O2
3. high pH, low CO2, low H+ ions
Characteristics of hemoglobin in the muscle: ......ANSWER.....1.
tense, domed state
2. low affinity for O2
3. low pH, High CO2, High H+ ions
Hemoglobin _____ to O2 at high pH and _______ O2 at low pH.
......ANSWER.....Hemoglobin binds to O2 at high pH and releases
O2 at low pH.
(It binds at high pH in lung to pick up oxygen and carry it tissues
and release it at low pH.)
These 3 things can be catabolized into Acetyl CoA
......ANSWER.....1. fatty acids
2. amino acids
,3|Page
3. glucose
How many ATP are produced for every molecule of glucose that is
aerobically metabolized? ......ANSWER.....30
What occurs in an exercising muscle under anaerobic conditions?
......ANSWER.....Pyruvate from glycolysis is turned into lactate in
order to regenerate NAD+ for further rounds of glycolysis, yielding
2 ATP per round for muscle use. The Cori Cycle allows lactate to be
turned into glucose via gluconeogenesis in the liver at the expense
of 6 ATP. Overall, the Cori Cycle creates a deficit of 4 ATP.
What happens if cyanide is consumed? ......ANSWER.....ADP will
build up, protons will not pump into intermembrane, and oxygen
will not be consumed by ETC.
What happens to pyruvate in the absence of oxygen?
......ANSWER.....In the absence of oxygen, pyruvate is transformed
to lactate by fermentation.
, 4|Page
The Cori Cycle occurs during ______. ......ANSWER.....exercise.
During the Cori Cycle, lactate produced by fermentation leaves the
cell and enters the blood. The liver cells take up the lactate from
the blood and use the gluconeogensis pathway to convert 2
molecules of lactate back to glucose.
3 functions of insulin: ......ANSWER.....1. stimulates gluclose uptake
2. inhibits glycogen breakdown
3. stimulates fatty acid production and storage
Glucogenolysis is stimulated when ____
......ANSWER.....Glucogenolysis is stimulated when glucagon enters
the bloodstream.
Where is the largest store of energy in the human body located?
......ANSWER.....triglycerides in adipose tissue
