They are produced by various organs in the digestive system, such as the salivary glands, stomach, pancreas, and small intestine. Enzymes catalyze specific chemical reactions and play a crucial role in the digestion and absorption of nutrients. To find this answer, you could have analyzed the function of each option and identified enzyme as the one that aligns with the description provided.
