Alcohol is produced during the process of

Products of anaerobic respiration are

The energy yield in terms of $ATP$ is higher in aerobic respiration than during anaerobic respiration. Why does anaerobic respiration occur even in organisms that live in aerobic conditions,such as human beings and angiosperms?

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

In anaerobic respiration,how many net $ATP$ molecules are formed from one glucose molecule?

In alcohol fermentation, . . . . . . of energy in glucose is released and not all of it is trapped as high energy bonds of $ATP$.
