Emulsion of fatty acids is necessary to .
a. break the intramolecular bonds
b. expose hidden bacteria in the fatty bolus
c. increase the surface area available for hydrolysis by lipase
d. trigger secretion of pancreatic enzymes
e. pass these molecules through the stomach

c. increase the surface area available for hydrolysis by lipase

Explanation:

Emulsification of fats(fatty acid) is a chemical reaction where large molecules(globules) of fats are broken down into a smaller molecules (droplets) by the action of an emulsifier.

In the human body, emulsification takes places in the duodenum during the process of digestion of fats. When large fat molecules have been broken down into smaller fat molecules by action of an emulsifier called bile salts from the gall bladder, a larger surface area is created which makes it possible for the enzyme lipase from the pancreas to react with or act on fat molecules through the process of hydrolysis thereby converting the fats to fatty acids and glycerol for use by the body.

Option C

Explanation:

The emulsification of fats is necessary so as to allow to easy break down of large molecules of fats into smaller droplets increasing their surface are such that enzymes like lipases can act on them, digest them breaking them down into fatty acids and glycerol to be easily absorbed by the small intestine.

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.
