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. Correct Answer: True
Nutrient that can not be broken down to a substance that can participate in the production of ATP via
aerobic cellular metabolism Correct Answer: Vitamin E
Glycolysis produces 2 ATP molecules, through what process are these ATP molecules made?
Correct Answer: Substrate level phosphorylation
What product of beta oxidation is able to enter the citric acid cycle? Correct Answer: AcetylCoA
What process is shared between anaerobic and aerobic metabolism? Correct Answer: glycolysis
A defect occurs that prevents pyruvate from converting to lactate under anaerobic conditions - what is
a possible consequence? Correct Answer: glycolysis stops because NAD+ levels are too low
What differentiates aerobic from anaerobic cellular metabolism? Correct Answer: utilization of 02 as
an electron acceptor
What takes place in the mitochondria of a cell? Correct Answer: 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 Answer: conversion of pyruvate to
lactic acid
Under aerobic conditions in a human, which molecule is formed in the cytosol by fermentation?
Correct Answer: 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 Answer:
improving glycogen stores in the liver and muscle
Which process is stimulated when glucagon is released into the bloodstream? Correct Answer:
triglyceride synthesis
Which chemical represents a monosaccharide? Correct Answer: 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 Answer: He is likely to have lost adipose tissue
and muscle mass
