Q. Under anaerobic conditions, oxidizing glucose can result in what waste product?
Water
Lactic acid
FADH2
NADH
ATP
Q. What compound appears at both the beginning and the end of the citric acid cycle?
Lactic acid
Ethanol
Oxaloacetate
Pyruvate
Oxygen
Q. What metabolic process is the most widespread among all living organisms?
Glycolysis
Electron transport chain
Oxidative phosphorylation
Alcohol fermentation
Lactic acid fermentation
Q. What molecule accepts the electrons from NADH in fermentation?
Ethanol
Pyruvate
Glucose
Carbon dioxide
ATP
Q. Oxygen is necessary for cellular respiration because
combustion cannot take place without oxygen
oxygen runs the ATP synthase motor
glycolysis depletes oxygen, and cellular respiration replenishes it
oxygen accepts electrons at the end of the electron transport chain
pyruvate cannot be made without it
Q. In the citric acid cycle, what occurs?
Acetyl-CoA enters the cycle, and ATP, NADH, and FADH2 are produced.
Pyruvate enters the cycle, and ATP, NADH, and FADH2 are produced.
Acetyl-CoA enters the cycle, and 38 ATP are produced.
NADH donates its electrons to a protein.
ATP synthase phosphorylates ADP to ATP.
Q. The citric acid cycle is so named because
no one could come up with a better name
citric acid is reduced in it
it produces citric acid as an end product
it was first identified in citrus fruits
acetyl-CoA joins up with oxaloacetate to make citric acid
Q. What process releases carbon dioxide (CO2)?
Alcohol fermentation
Lactic acid fermentation
The citric acid cycle
A and B
A and C
Q. Which of the following is true?
All living things use oxygen during respiration.
Oxygen is used to oxidize glucose.
Only yeast do anaerobic respiration.
The bulk of ATP synthesis happens in chemiosmosis.
Glucose is produced through respiration.
Q. Fermentation produces
as much ATP as aerobic respiration
less ATP than aerobic respiration
more ATP than aerobic respiration
no ATP
variable amounts of ATP depending on the input.
