Genetically modified bacteria are grown in a fermenter to produce human insulin. A pump supplies air to the culture.
The pump begins to deliver less air, but the glucose supply and temperature stay the same.
What is the most likely change in the fermenter?
The bacteria grow faster because less glucose is used in aerobic respiration
The bacteria grow more slowly because less oxygen is available for aerobic respiration
The bacteria grow at the same rate because the glucose supply has not changed
The bacteria make a different protein because the inserted gene changes when airflow falls
