Bacteria that only use fermentation for their energy are ____

Obligate anaerobes lack the ability to _____

Aerotolerant bacteria have the ability to _____

______ require oxygen for survival and cellular respiration

______ obtain their energy from fermentation (or cellular anaerobic respiration)

_______ contain the enzymes to carry out cellular repiration and fermentation, depending on the presence or absence of oxygen

Bacteria that prefer to do aerobic cellular respiration over fermentation because they obtain more ATP that way

_____ do not use oxygen, but have the enzymes to detoxify it. They ferment for energy.

______ do not have the enzymes to detoxify reactive oxygen species, and therefore will not survive in an oxygen-rich environment. They ferment for energy

______ have a small amount of enzymes for detoxifying reactive oxygen species, so they can grow when there is a small amount of oxygen present. They mostly ferment

The most common products of fermentation are ____ and _____
