Question

One of the effects of the hormone secretin is to stimulate the release of bicarbonate ions into the duodenum, which neutralizes the acid that enters the duodenum with food from the stomach. One consequence of neutralizing the pH in the intestine is that: the enzymatically catalyzed hydrolysis of carbohydrate that began in the stomach is halted in the duodenum. carbohydrates are not as easily broken down in this neutral environment. enzymes that catalyze the hydrolysis of carbohydrates are active. enzymes that catalyze the hydrolysis of carbohydrates are denatured

Answer 1

Answer: One consequence of neutralizing the pH in the intestine is that ENZYMES THAT CATALYZE THE HYDROLYSIS OF CARBOHYDRATES ARE ACTIVE.

Explanation: During digestion, partially digested food particles are transported from the stomach to the first part of the small intestines, that is, the duodenum. The food particles that are coming from the stomach are acidic due to the secretion of hydrochloric acid in the stomach. This acidity has to be removed when the food particles get into the duodenum, this is because the enzymes that are needed to break down carbohydrates in the duodenum can not work in acidic medium. Thus, in order for the pancreatic amlayse enzyme to become active and to complete the break down of carbohydrate in the duodenum, the secretin hormone has to stimulate the release of bicarbonate that will neutralize the acidic partially digested food particles from the stomach.
