b. enzymes that are released when food en-ters the small intestine.

D
Hormones that are released when chime enters the small intestine cause the release of digestive secretions into the small intestine. Hormones control the release of digestive secretions; digestive secretions contain enzymes that digest macronutrients. The hormones that signal release of di-gestive secretions into the small intestine are triggered when chime enters the small intestine. If they were released when food entered the stomach, digestive secretions would be released into the small intestine too early and could cause damage.
