Concept explainers
(a)
Interpretation: To identify whether gastrin is a hormone, a digestive enzyme or neither a hormone nor a digestive enzyme.
Concept introduction: Enzymes are specialized proteins that act as biological catalysts. Enzymes accelerate the biochemical reactions to produce the substances that are needed for cells for their proper functioning. The enzymes are very specific to their action.
Hormones are the chemical signals and these are produced by specialized cells. Hormones are secreted into the blood stream and carried to a target tissue where they signal the targeted tissue or organ to perform their specified function.
(b)
Interpretation: To identify whether trypsin is a hormone, a digestive enzyme or neither a hormone nor a digestive enzyme.
