Which of the following can perform anaerobic respiration?

Explanation

All the options listed-bacteria, yeast, and skeletal muscles-are capable of performing anaerobic respiration under certain conditions. Bacteria often use this process in environments lacking oxygen, employing various biochemical pathways. Yeast performs fermentation, a type of anaerobic respiration, to produce energy in oxygen-deprived environments. Skeletal muscles can switch to anaerobic respiration during strenuous activities when oxygen is limited, producing lactic acid as a byproduct. Thus, the correct answer is 'All of these,' since each of these organisms can perform anaerobic respiration, albeit through different mechanisms and for varied purposes.
