Explanation:
These organisms likely have very low energy requirements. Given that each round of fermentation produces limited ATP, the organism has likely adapted its energy requirements in response.
During glycolysis, in the cytoplasm, enzymes act on the substrate, glucose. The covalent bonds of the macromolecule contain energy that is released and stored within ATP.
Glycolysis occurs in the cytoplasm; here, 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules.
Further Explanation:
In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).
overall aerobic respiration: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP
In the absence of oxygen however, fermentation may occur to produce 2 net ATP
lactic acid fermentation: C6H12O6 → 2 CH3CHOHCOOH + 2 ATP
