What is the main purpose of glucose catabolism? - ANS✔✔to transfer energy from
glucose to ATP
Glycolysis, anaerobic fermentation, and aerobic respiration are the three major
pathways for the catabolism (breakdown) of: - ANS✔✔glucose
The addition of an inorganic phosphate (Pi) group to an organic molecule is a process
called: - ANS✔✔phosphorylation
Which process yields a net gain of 2 ATP per glucose molecule? - ANS✔✔Glycolysis
Unlike aerobic respiration, anaerobic fermentation may occur under which of the
following conditions? - ANS✔✔When no oxygen is available
The products of complete glucose catabolism (oxidation) include: - ANS✔✔carbon
dioxide, water and ATP
What are the three major pathways by which glucose is catabolized in the human body?
- ANS✔✔Glycolysis
Anaerobic fermentation
Aerobic respiration
What occurs in the reaction called phosphorylation? - ANS✔✔Addition of inorganic
phosphate to an organic molecule
Anaerobic fermentation results in pyruvic acid being reduced to: - ANS✔✔lactic acid
The process of glycolysis results in net gain of how many molecules of ATP? -
ANS✔✔2
In the absence of oxygen, small amounts of ATP may be produced via an anaerobic
process called: - ANS✔✔fermentation
Lactic acid is converted back to pyruvate in which organ? - ANS✔✔liver
In the presence of oxygen, ____________ acid enters the mitochondria and is oxidized
by aerobic respiration. - ANS✔✔pyruvic
In anaerobic fermentation, NADH donates a pair of electrons to ______ acid, thus
reducing it to ______ acid and regenerating NAD. - ANS✔✔pyruvic, lactic
What is the cellular location for the Krebs cycle? - ANS✔✔Mitochondria
What is a series of oxidation reduction reactions occurring across the inner membrane
of the mitochondria leading to the production of ATP? - ANS✔✔the electron transport
chain
What is the electron transport chain? - ANS✔✔a series of oxidation reduction reactions
occurring across the inner membrane of the mitochondria leading to the production of
ATP
The liver oxidizes lactic acid back to ____________ acid, which can then enter the
aerobic pathway when oxygen becomes available again. - ANS✔✔pyruvic
