Q

which of the following is true, comparing lactic acid fermentation, alcoholic fermentation, and aerobic respiration:
a
Human cells usually use aerobic respiration when there is plenty of oxygen. They use lactic acid fermentation when there is not very much oxygen available

b
Yeast can use either aerobic respiration or alcoholic fermentation, depending on oxygen availability

c
Aerobic respiration produces significantly more ATP per glucose than either form of fermentation does

d
Pyruvate accepts an e- from NADH in lactic acid fermentation, regenerating the NADH to NAD+

Q

Which of the following are true comparing catabolic and anabolic pathways:

c
nucleotides can be made from intermediates of cellular respiration, despite not being used as an energy source for cellular respiration
