Question

Anaerobic bacteria are bacteria only active in the presence of free oxygen. True or False?

1) True
2) False

Answer 1

The statement 'Anaerobic bacteria are bacteria only active in the presence of free oxygen' is False. Anaerobic bacteria are actually organisms that are only active in the absence of free oxygen.

Step-by-step explanation:

The statement 'Anaerobic bacteria are bacteria only active in the presence of free oxygen' is False. Anaerobic bacteria are actually organisms that are only active in the absence of free oxygen. These bacteria are capable of carrying out anaerobic respiration or fermentation to produce ATP when oxygen is not available. They lack the enzymes needed to protect themselves from oxidative stress caused by oxygen free radicals.
