Ryan Chang · Answer 1

a. The organism goes through fermentation.

Explanation:

If the organism does not have mitochondria, it won't be able to go through cellular respiration (requires oxygen). This is due to the electron transport chain (last part of aerobic cellular respiration) is carried in mitochondrial inner membranes. Therefore, options b, c, and d are wrong.

The right answer is option a. Fermentation is carried by prokaryotes than don't have inner membranes, so they don't have organelles, therefore, they don't have mitochondria.
