question
The oxygen consumed during cellular respiration is involved directly in which process or event?
answer
Accepting electrons at the end of the electron transport chain
question
Which of the following events takes place in the electron transport chain?
answer
The extraction of energy from high-energy electrons remaining from glycolysis and the citric acid cycle
question
Which of the following produces the most ATP when glucose (C6H12O6) is completely oxidized to carbon dioxide and water?
answer
Oxidative phosphorylation (Chemiosmosis)
question
In liver cells, the inner mitochondrial membranes are about five times the area of the outer mitochondrial membranes. What purpose must this serve?
answer
It increases the surface for oxidative phosphorylation.
question
Inside an active mitochondrion, most electrons follow which pathway?
answer
Citric acid cycle → NADH → electron transport chain → oxygen
question
Why is ATP production during cellular respiration characterized as indirect?
answer
ATP is not produced directly by the ETC but instead via the proton gradient generated during electron transport through the ETC.
question
Which metabolic pathway is common to both cellular respiration and fermentation?
answer
Glycolysis
