Answer:
Type A respiration does not require oxygen, but Type B respiration requires oxygen.
Explanation:
Lactic acid is only produced in anaerobic cell respiration, also called fermentation. As the name says, this breathing does not require the presence and oxygen. In fact, anaerobic cellular respiration is performed by beings that live in oxygen-free environments, which are some microorganisms.
Aerobic cellular respiration, on the other hand, generates a large amount of energy, called ATP, and is performed in the presence of oxygen, being performed by most living beings, including us humans.
