Which statement best describes respiration in spiral shaped bacteria?
a. spiral shaped bacteria only utilize aerobic respiration
b. spiral shaped bacteria are facultative anaerobes but can switch to anaerobic repiration when needed
c. spiral shaped bacteria are generally aerobic, but a subset of the group uses anaerobic repiration
d. spiral shaped bacteria only utilize anaerobic repiration

1 answer

The best statement that describes respiration in spiral shaped bacteria is:

c. spiral shaped bacteria are generally aerobic, but a subset of the group uses anaerobic respiration.

This option acknowledges that while many spiral-shaped bacteria (such as spirochetes) are primarily aerobic, some can also carry out anaerobic respiration depending on environmental conditions.
