Lactic acid
During the anaerobic phase of respiration, glucose is converted into pyruvate through a process called glycolysis. This process does not require oxygen and occurs in the cytoplasm of the cell. If oxygen is not present, pyruvate can then be further converted into lactic acid (in animals) or ethanol and carbon dioxide (in some microorganisms) to generate a small amount of ATP.
Pyruvate is converted into acetyl-CoA in the mitochondrial matrix through the process of pyruvate oxidation. Acetyl-CoA then enters the citric acid cycle to produce reducing equivalents (NADH and FADH2) and ATP through oxidative phosphorylation.
During anaerobic respiration, cells produce energy without the presence of oxygen. The process begins with glycolysis, where glucose is broken down into pyruvate. In the absence of oxygen, pyruvate is converted into either lactic acid in animals or alcohol and carbon dioxide in yeast and some bacteria, generating a small amount of ATP.
The reactants for anaerobic cellular respiration are glucose molecules, which are broken down into pyruvate molecules. The end products of anaerobic respiration in animals is lactic acid, while in certain bacteria and yeast, the end product is ethanol and carbon dioxide.
The purpose of fermentation reactions after glycolysis is to regenerate NAD+ so that glycolysis can continue producing ATP in the absence of oxygen. Fermentation allows for the conversion of pyruvate into different end products (such as lactate or ethanol) to maintain cellular energy production in anaerobic conditions.
In anaerobic respiration, glucose is partially broken down into pyruvate through glycolysis. Pyruvate is then converted into lactic acid in animals or ethanol in microorganisms, with no oxygen required for this process. This allows for the production of ATP in the absence of oxygen.

The five compounds associated with anaerobic respiration are glucose (substrate), pyruvate (end product of glycolysis), lactate (end product in animals), ethanol (end product in yeast), and ATP (energy currency produced).

Anaerobic animals (and other substances) survive without oxygen.
If there is no oxygen available after glycolysis, anaerobic respiration occurs. This process involves the conversion of pyruvate into lactic acid (in animals) or ethanol (in yeast and some bacteria) to regenerate NAD+ and continue ATP production. Anaerobic respiration is less efficient than aerobic respiration in terms of ATP production.
Aerobic and anaerobic
No, plant cells can also undergo anaerobic respiration under low oxygen conditions. Some animals, like certain species of fish and insects, can also use anaerobic respiration when oxygen levels are limited.
The products of aerobic respiration are water and carbon dioxide. The products of anaerobic respiration are carbon dioxide and either lactic acid or alcohol. The waste product of anaerobic respiration is lactic acid (in animals). In plants, ethanol is the waste product.
