Question

in humans, bile breaks lipids into three fatty acids and one glycerol molecule true or false

Answer 1

False. Lipids are the monomer. Therefore you cannot break down a monomer to get polymers. You can only break down polymers to get monomers.

Answer 2

False.
Bile is produced in the liver, temporarily stored in the gall bladder
and released into the duodenum through the bile duct. Bile is a
green, alkaline fluid. It contains no digestive enzymes, but
contains:

1. bile salts, which emulsify lipids, i.e. breaking them up into
small droplets. This increases the surface area for the enzyme
lipase (secreted by pancreas) to act on, thereby speeding up the digestion of lipids.

2. sodium hydrogencarbonate,which makes the bile alkaline. It
neutralises the acidic chyme from the stomach and provides
an optimum pH of 7.6 to 8.6 for intestinal enzymes.

3. bile pigments, which are the breakdown products of
haemoglobin from red blood cells in the liver. They give bile
its green colour, but have no digestive functions.

To conclude, bile does not break lipids into three fatty acids and one glycerol molecule, as it only emulsifies lipid into smaller oil droplets. Only lipase does the breakdown job ;)
