When some bacteria use lactose as a source of energy, they produce propionic acid and CO₂. What is the name for this process? A) cellular respiration B) carbon fixation C) chemical synthesis D) photosynthesis E) fermentation

Question

Quizplus · Accepted Answer

The production of propionic acid and CO₂ from lactose is a characteristic of fermentation, which is the process used by some bacteria (such as lactic acid bacteria) to generate energy in the absence of oxygen. The other choices (cellular respiration, carbon fixation, chemical synthesis, and photosynthesis) are not applicable to this situation.
