What chemical Substances Control Digestion?

Several chemical substances play crucial roles in digestion, primarily enzymes and hormones. Enzymes, such as amylase, proteases, and lipases, break down carbohydrates, proteins, and fats, respectively. Hormones like gastrin, secretin, and cholecystokinin regulate digestive processes by signaling the release of digestive juices and bile. Additionally, hydrochloric acid in the stomach aids in food breakdown and creates an acidic environment for enzyme activity.
