Question

in some lower organisum that occurs anearobic respiration how this process occurs what are the bi-products form? plz answer this question its urgent i will mark u as brainlist

Answer 1

There are 2 major type of anaerobic respiration, Lactic Acid Fermentation and Alcoholic Fermentation.

Alcoholic Fermentation occurs in yeast (unicellular fungi).
In this, pyruvate (product of glycolysis) is first broken down into acetaldehyde and CO2 in presence of enzyme pyruvate decarboxylase. Then, acetaldehyde is converted into ethanol in the presence of enzyme alcohol dehydrogenase. So the product is Ethanol.

Lactic Acid Fermentation is found in Lactic Acid Bacteria (Lactobacillus lacti)
In this, pyruvate is converted into Lactic Acid in presence of enzyme Lactic Acid dehydrogenase. So, the product is Lactic Acid.


Note:- Lactic Acid Fermentation also occurs in our skeletal muscles when there is inadequate supply of oxygen causing muscle fatigue.

Answer 2

The end products of anaerobic respiration are Lactic acid or ethanol and ATP molecules. Anaerobic respiration takes place in the absence of oxygen and is seen in lower animals. During the process of Anaerobic Respiration in prokaryotes, there is a breakdown of glucose to produce energy for cellular activities.
