Anaerobic respiration was first of all reported by

Glucose breakdown takes place ... in fermentation.

The number of $ATP$ produced when a molecule of glucose undergoes fermentation is

During anaerobic respiration in a prokaryotic cell,what is the net gain of $ATP$ molecules from one molecule of glucose?

Organism which can respire in the absence of $O_2$ is

In animal cells,like muscle,during exercise when $O_{2}$ is inadequate for cellular respiration,pyruvic acid is reduced into lactic acid by
