  Yes, humans can and do undergo anaerobic respiration, specifically in muscle cells during intense physical activity when oxygen supply is limited. This process, also known as fermentation, allows muscles to generate energy (ATP) even without sufficient oxygen, although it is less efficient than aerobic respiration. The byproduct of this process in humans is lactic acid, which can lead to muscle fatigue and cramps.
