Explain how the fluid mosaic model describes the plasma membrane

S.J. Singer and Garth L. Nicolson proposed the fluid mosaic model to describe the plasma membrane structure. They explained that the plasma membrane is a mosaic of carbohydrates, phospholipids, carbohydrates, and proteins.

This mosaic nature provides the fluid characteristic to the plasma membrane. This fluid behavior of the plasma membrane allows the movement of phospholipids and protein in the plasma membrane.  

This movement of membrane components plays an important role in the transport of molecules across the cell.

explanation:

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
