Question

1. evaluate the claim that oxygen is required to produce large amounts of atp during cellular respiration. which observation best supports this claim? 1 a. yeast produced more foam in bottles with less oxygen. b. human cells only use anaerobic respiration. c. aerobic respiration produces more atp than anaerobic. d. oxygen levels have no effect on atp production.

Explanation:

Aerobic respiration in yeast produces more foam in bottles with less oxygen as yeast can perform both aerobic and anaerobic respiration. Human cells mainly use aerobic respiration and produce more ATP in it compared to anaerobic. Anaerobic respiration produces less ATP than aerobic. Oxygen levels have an effect on ATP production. Option a best supports the claim that oxygen is required to produce large amounts of ATP during cellular respiration as it shows yeast - a model organism - producing more foam (a sign of metabolic activity) in conditions with less oxygen, indicating its need for oxygen to carry out more efficient respiration and produce more ATP.

Answer:

a. Yeast produced more foam in bottles with less oxygen.
