A student performed an activity to show that lipase, an enzyme produced in the pancreas, does in fact hydrolyze fats into glycerol and fatty acids. The student was provided with the following materials:
Materials
- whole milk (cereal cream)
- lipase solution
- 3 - 25 mL test tubes
- phenolphthalein (phenolphthalein is a pH indicator that is pink in a base and colourless in an acid)
- dish soap
- 10% sodium bicarbonate solution (NaHCO3)
- 3 rubber stoppers
- medicine droppers
- test tube holder
- wax pencil
- 37 °C hot water bath
Use the information above to answer the next four question
Design an experiment demonstrating that lipase digests milk to produce an acid andthat emulsification is important in the digestion of lipids. Write the steps of a procedure in the space below. Be sure to include a control test in the procedure.
Explain the purpose of the milk, the soap, the sodium bicarbonate, and the water bath in this investigation
identify the test tube that would show the fastest reaction, and explain why.
