Question

what is Fermentation respiration? ​

Answer 1

$\underline{\huge{Answer}}$

____________________________

Fermentation :-

(In yeast) the complete oxidation of glucose is achieved under anaerobic conditions by sets of reactions where pyruvic acid is converted to CO2 and ethanol .The enzymes pyruvic acid decarboxylase and alcohol dehydrogenase catalyse these reactions other organisms like some bacteria produce lactic acid from pyruvic acid

In animal cells also , like muscles during exercise when oxygen is inadequate for cellular respiration pyruvic acid is reduced to lactic acid by lactate dehydrogenase .The reducing agent is NADH+ H+ which is re oxidized to NAD+ in both the processes.

In both lactic acid and alcohol fermentation not much energy is released less than 7% of the energy in glucose is released and not of of it is trapped as high energy bonds of ATP..
