questions
The polysaccharide cellulose is composed of sugar monomers linked through beta linkages, with
their CH2OH groups in opposite direction relative to the neighboring monomer. -✔✔True
Nutrient that can not be broken down to a substance that can participate in the production of ATP
via aerobic cellular metabolism -✔✔Vitamin E
Glycolysis produces 2 ATP molecules, through what process are these ATP molecules made? -
✔✔Substrate level phosphorylation
What product of beta oxidation is able to enter the citric acid cycle? -✔✔AcetylCoA
What process is shared between anaerobic and aerobic metabolism? -✔✔glycolysis
A defect occurs that prevents pyruvate from converting to lactate under anaerobic conditions - what
is a possible consequence? -✔✔glycolysis stops because NAD+ levels are too low
What differentiates aerobic from anaerobic cellular metabolism? -✔✔utilization of 02 as an electron
acceptor
What takes place in the mitochondria of a cell? -✔✔production of FAHD2
production of CO2 in the citric acid cycle
creation of a proton gradient
What does not take place in the mitochondria of a cell? -✔✔conversion of pyruvate to lactic acid
Under aerobic conditions in a human, which molecule is formed in the cytosol by fermentation? -
✔✔lactate
, A woman is about to begin her ascent of Mount Everest and is preparing for Day 1 of the climb.
Approximately 6 hours before the hike begins, she and her climbing team eat a meal containing 80%
complex carbohydrates. What is the physiological benefit of this approach? -✔✔improving glycogen
stores in the liver and muscle
Which process is stimulated when glucagon is released into the bloodstream? -✔✔triglyceride
synthesis
Which chemical represents a monosaccharide? -✔✔C6H1206
A patient with advanced cancer has not been able to eat a full meal for the past 3 months, and his
intake has gradually diminished over the last month such that his entire intake in the prior 3 days
consists solely of water. What is most likely? -✔✔He is likely to have lost adipose tissue and muscle
mass
Which process is stimulated when insulin is released into the bloodstream? -✔✔glycogenesis
What is the largest source of energy storage in the normal human body? -✔✔triglycerides in adipose
What drives glucose from the bloodstream into the cells? -✔✔insulin
What chemicals can be produced in dangerous excess in a patient taking metformin because of its
effects of decreasing the liver's participation in the Cori Cycle? -✔✔lactic acid
A 2-year old boy found to have an autosomal recessive glycogen storage disease that prevents him
from being able to fully metabolize glucose. On examination, he has an enlarged liver and bulky
appearing muscles. Biopsy of both the liver and the muscles shoes markedly increased amounts of
glycogen compared to normal - What is true? -✔✔Since glucose can be partially but not fully
metabolized, there is an increased concentration of the intermediate compounds and this causes a
shift in enzymatic reactions, favoring the production of glycogen
Sucrose is a disaccharide consisting of one molecule of glucose bound to one molecule of fructose.
When you put sucrose in your tea, how is that sucrose utilized by your body for making energy? (ATP)
-✔✔sucrose is broken down into its constituent monosaccharides for absorption, these can then be
metabolized via glycolysis and the citric acid cycle
