The solutions in the two arms of this U-tube are separated by a membrane that is permeable to water and glucose but not to sucro
Gnom [1K]

Initially, in terms of tonicity, the solution in side A with respect to that in side B is isotonic.

  • A solution is considered to be isotonic if it possesses the same osmolarity, or level of solute concentration, as another solution. When these two solutions are placed on either side of a membrane that is only partially permeable to water, water will flow in an equal amount from one solution into the other. The result is that there is no water flow at all between the two solutions, despite the fact that water is travelling in both directions.
  • A solution is considered hypotonic when it has a lower level of solute concentration in comparison to another solution.
  • A solution is considered hypertonic when it has higher osmolarity compared to another solution.

In the given questions, the solution in the two arms of the U- tube has the same osmolarity and therefore is isotonic.

in the adult digestive tract, where do lipases break fat into fragments so that it can be absorbed into the lymph?
Strike441 [17]

As to the digestive tract, the function of the lipases would take place in the small intestine.

Lipase is an enzyme that helps us to <u>metabolize fat</u>. It does this through <u>hydrolysis</u>. Although in reality, as an enzyme, its main function is to catalyze this process. Lipases are the subclass enzyme of the esterases.

Lipases are necessary for the proper digestion and transport of fats in the form of lipids. They are also essential to process these lipids in the human body. This enzyme is present in most living organisms outside of humans.

Although lipase enzymes are produced throughout the body, the bulk of lipase production occurs in the pancreas. It will then travel to the small intestine to carry out its functions in the digestive tract.
