Answer:
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.
What are the choices to choose from? (It says "which of the following")
The correct answer for this question is C - the best description of a
chemical reaction from the answers offered here is that it consists of
the forming and breaking of bonds between particles. There are not any
atoms destroyed in a chemical reaction, so B and C are incorrect, and
although mixing two substances together (as specified in A) could
produce a chemical reaction, this is not the best way of describing the
actual chemical process.
Answer:
Km is the Michaelis-Menten constant which shows the concentration of the substrate when the reaction velocity is equal to one half of the maximal velocity for the reaction. It can also be thought of as a measure of how well a substrate complexes with a given enzyme, otherwise known as its binding affinity.
