The given statement is true that fermentation provides energy for cells without using oxygen.
Fermentation is the process where the organic molecules like sugar are broken down to form acid, alcohol or gases like carbon dioxide. The sugar is first broken down by the process of glycolysis and then further fermentation process occurs in the absence of oxygen. The process occurs in anaerobic organisms as well as in muscles of humans.
Energy is the most essential component to carry out all the metabolic processes of the living body. The most prevalent form of energy used is ATP. This is formed in the cell organelle mitochondria.
