Plants : ________:: Animals: Lactic Acid

End products of anaerobic respiration:

1. The end products of anaerobic respiration are lactic acid or ethanol and ATP molecules in animals and plants respectively.
2. In the absence of oxygen anaerobic reputation occurs in lower animals.

Anaerobic respiration:

1. The process of respiration that occurs in the absence of oxygen is known as anaerobic respiration.

Lactic acid fermentation (Animals):

${\mathrm{C}}_6{\mathrm{H}}_{12}\mathrm{O}\to 2{\mathrm{C}}_3{\mathrm{H}}_6{\mathrm{O}}_3+2\mathrm{ATP}$

glucose lactate

Alcoholic fermentation (Plants):

${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\to 2{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}+2{\mathrm{CO}}_2+2\mathrm{ATP}$

glucose. alcohol

Final answer: Plants :Ethanol:: animals: Lactic Acid
