In an experiment, lipase is added to milk in a test tube containing a pH indicator that is purple at pH 8 and turns yellow at pH 5. After 15 minutes at 37 °C, the mixture turns yellow. What is the best explanation?
- Lipase converts fats into amino acids, increasing pH.
- Lipase converts fats into fatty acids, decreasing pH.
- Lipase converts fats into glucose, decreasing pH.
- Lipase is denatured, so the pH indicator changes randomly.
