Question

Quizplus · Accepted Answer

Stomach cells also secrete mucus, which helps protect the stomach lining from the harsh effects of the hydrochloric acid. Bile is produced in the liver and stored in the gallbladder before being released into the small intestine to aid in fat digestion. Amylase is produced in the pancreas and small intestine to break down carbohydrates, and lipoproteins are a type of molecule that transport lipids in the body. These are not directly secreted by the stomach cells. Therefore, only choice A is correct. The stomach cells also secrete mucus, which serves to protect the stomach lining from the acidic environment created by hydrochloric acid. Bile is produced by the liver and stored in the gall bladder, and is not directly secreted by stomach cells. Amylase is an enzyme produced by the pancreas and salivary glands, not stomach cells. Lipoproteins are not directly secreted by stomach cells.
