Question 28 1 pts Complete the following sentence: As a general rule, the stomach empties chyme... O into the esophagus when the particles are about 1 mm in diameter O when the chyme is very acidic at a rate of 2 kcal/hr using segmentation contractions

Answer 1

Answer:-

=> Chyme is the pulpy acidic fluid or  semi-fluid mass which passes from the stomach to the small intestine, consisting of gastric juices and partly digested food.

Hence, the correct option is when the chyme is very acidic.

=> In the duodenum, digestive secretions from the liver, pancreas, and gallbladder play an important role in digesting chyme during the intestinal phase. In order to neutralize the acidic chyme, a hormone called secretin stimulates the pancreas to produce alkaline bicarbonate solution and deliver it to the duodenum.

Hence, the correct option is Proteins are denatured by pancreatic bicarbonate.
