✔✔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

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

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
