please answer questions 1 & 2
If the following mixtures are incubated at 37°C with the addition of enzymes and/or bile salts, predict if the mixtures would increase in acidity and, if so, which samples increased the most. If the lipids are not digested to a great extent, there would be little change in acidity. Table 5: Testing after incubation with pancreatin or pancreatin and bile salts Test tube Substance Enzyme Prediction of drops of NaOH solution to neutralize (no...

please help me with this experiment???
Enzymes Experiment 1: Enzymes in Food Amylase is used by humans to facilitate digestion. Specifically, it is an enzyme that breaks down starch molecules into sugar molecules. This is why people sometimes observe a sweet taste after sucking on a starch-containing food for an extended period of time. Amylase is found naturally in human saliva and the pancreas. However, it is also present in some of the common plant foods consumed by humans. This...
