UPDATE)/GRADED A+
The polysaccharide cellulose is composed of sugar monomers linked through beta linkages, with their
CH2OH groups in opposite direction relative to the neighboring monomer. (correct answers)True
Which are the nutrients that can not be broken down to a substance that can participate in the
production of ATP via aerobic cellular metabolism? (correct answers)Vitamin E
Glycolysis produces 2 ATP molecules, through what process are these ATP molecules made? (correct
answers)Substrate level phosphorylation
What product of beta oxidation is able to enter the citric acid cycle? (correct answers)AcetylCoA
What process is shared between anaerobic and aerobic metabolism? (correct answers)glycolysis
A defect occurs that prevents pyruvate from converting to lactate under anaerobic conditions - what is a
possible consequence? (correct answers)glycolysis stops because NAD+ levels are too low
What differentiates aerobic from anaerobic cellular metabolism? (correct answers)utilization of 02 as an
electron acceptor
What takes place in the mitochondria of a cell? (correct answers)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? (correct answers)conversion of pyruvate to
lactic acid
Under aerobic conditions in a human, which molecule is formed in the cytosol by fermentation? (correct
answers)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? (correct answers)improving
glycogen stores in the liver and muscle
Which process is stimulated when glucagon is released into the bloodstream? (correct
answers)triglyceride synthesis
Which chemical represents a monosaccharide? (correct answers)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? (correct answers)He is likely to have lost adipose tissue and muscle
mass
Which process is stimulated when insulin is released into the bloodstream? (correct
answers)glycogenesis
What is the largest source of energy storage in the normal human body? (correct answers)triglycerides
in adipose
What drives glucose from the bloodstream into the cells? (correct answers)insulin
