Which of the following correctly describes fermentation?

• incomplete oxidation of glucose

• utilizes glycolysis, the krebs cycle, and the electron transport chain (respiratory)

• oxygen is not required

• uses NO-3, SO42-, CO33- (nitrate, sulfate, carbonate) and other oxidized inorganic compounds as terminal electron acceptors

• organic compounds are terminal electron acceptors

How does anaerobic respiration differ from aerobic respiration?

• Anaerobic respiration uses oxygen as the final electron acceptor, while aerobic respiration uses other oxidized inorganic compounds

• Anaerobic respiration uses other oxidized inorganic compounds as the final electron acceptor, while aerobic respiration uses oxygen

• Anaerobic respiration does not require oxygen, while aerobic respiration does

• Anaerobic respiration produces more ATP than aerobic respiration

Which of the following correctly describes anabolism?

• any process that results in synthesis of cell molecule and structures

• a building and bond-making process that forms larger macromolecules from smaller ones

• requires the input of energy (endergonic)

• breaks the bonds of larger molecules into smaller molecules

• releases energy (exergonic)

Which kind of metabolism is exergonic (releases energy)?

• anabolism

• catabolism

Metabolism uses ​ (a)   to ​ (b)   organic molecules to precursor molecules that cells then use to ​ (c)   ​ (d)   , more complex molecules

• enzymes

• chemical bonds

• catabolize

• inorganic molecule

• anabolize

• larger

• smaller

Answer explanation

• Produced during catabolism and needed in large quantities for anabolism:

• Reducing power: electrons available in NADH and FADH2

Which of the following correctly describes Aerobic respiration?

• a series of reactions that convert glucose to CO2 and allows the cell to recover significant amounts of energy

• utilizes glycolysis, the krebs cycle, and the electron transport chain (respiratory)

• relied on free oxygen as the final electron and hydrogen acceptor

• uses NO-3, SO42-, CO33- (nitrate, sulfate, carbonate) and other oxidized inorganic compounds as terminal electron acceptors

• organic compounds are terminal electron acceptors
