BioChem C785 - WGU - Module 4 - all questions 1.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
2.Nutrient that can not be broken down to a substance that can
participate in the production of ATP via aerobic cellular metabolism:
Vitamin E 3.Glycolysis produces 2 ATP molecules, through what process are
these ATP molecules made?: Substrate level phosphorylation
4.What product of beta oxidation is able to enter the citric acid cycle?:
Acetyl- CoA
5.What process is shared between anaerobic and aerobic metabolism?:
gly- colysis 6.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
7.What differentiates aerobic from anaerobic cellular metabolism?:
utilization of 02 as an electron acceptor
8.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 1 / 2
- / 5
9.What does not take place in the mitochondria of a cell?: conversion
of pyruvate to lactic acid 10.Under aerobic conditions in a human, which molecule is formed in
the cytosol by fermentation?: lactate
11.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 12.Which process is stimulated when glucagon is released into the
blood- stream?: triglyceride synthesis
13.Which chemical represents a monosaccharide?: C6H1206
14.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
