Answer :
Anaerobic respiration is a kind of respiration that takes place when oxygen is scarce. During intense activity, lactic acid builds up in the anaerobic respiratory system.
Through the cell's cytoplasm's electron transport chain, organic and biological fuel are broken down and oxidized during anaerobic respiration. Due to the increased energy demand during intense activity, the anaerobic respiration cellular process lacks the utilization of oxygen to make energy like ATP and lactic acid buildup. Carbon dioxide, water, lactic acid, and ATP are all produced as byproducts of the anaerobic respiration cellular process. When glucose and glycogen are broken down, lactic acid is created.
