Answer:
The breakdown of glucose in the absence of oxygen is termed as anaerobic respiration.
Explanation:
Anaerobic respiration or anaerobic oxidation occur in absence of oxygen molecule within the cytoplasm of cell that ultimately leads to the formation of lactate from pyruvate by the catalytic activity of lactate dehydrogenase enzyme.This reaction helps in the regeneration of NAD+.
During Anaerobic respiration only 2 molecules of ATP are formed by substrate level phosphorylation .
Lipids are much denser than water so they often " float " on water and also because that lipids and water can not dissolve to form a solution. lipids always tend to remain at top of water since they are denser .
