During the respiration of an organism $A$,one molecule of glucose produces two $ATP$ molecules,whereas in the respiration of another organism $B$,one molecule of glucose produces $38$ $ATP$ molecules.
$(a)$ Which organism is undergoing aerobic respiration?
$(b)$ Which organism is undergoing anaerobic respiration?
$(c)$ Which type of organism,$A$ or $B$,can convert glucose into alcohol?
$(d)$ Name one organism which behaves like $A$.
$(e)$ Name two organisms which behave like $B$.

(A) Organism $B$ is undergoing aerobic respiration because it produces a high yield of $38$ $ATP$ molecules per glucose molecule.
$(b)$ Organism $A$ is undergoing anaerobic respiration because it produces a low yield of only $2$ $ATP$ molecules per glucose molecule.
$(c)$ Organism $A$ can convert glucose into alcohol through the process of fermentation.
$(d)$ Yeast is an organism that behaves like $A$ (undergoes anaerobic respiration).
$(e)$ Human beings and aerobic bacteria are two examples of organisms that behave like $B$ (undergo aerobic respiration).
