3.Explain why pancreatic lipase would be active in both the mouth and the intestine?

Pancreatic lipase is most active at pH 7.0 The pH of the mouth is 7.0 & the pH of the small intestine is close to 8.0 so the enzyme would function in both places.

Fat globules are separated into droplets by bile salts through an emulsification process which is physical not chemical, which promote lipase activity.
