Questions: Question 88 (1 point) Gastric juices are a combination of mucous, pepsinogen and: hydrogen and chloride ions (forms hydrochloric acid) gastrin chyme amylase glucose

The answer is the first one: hydrogen and chloride ions (forms hydrochloric acid).

Explanation for each option:

• Hydrogen and chloride ions (forms hydrochloric acid): Correct. Gastric juices contain hydrochloric acid, which is formed from hydrogen and chloride ions. This acid is crucial for digestion as it helps break down food and provides an acidic environment for enzymes to function.
• Gastrin: Incorrect. Gastrin is a hormone that stimulates the secretion of gastric acid, but it is not a component of gastric juices.
• Chyme: Incorrect. Chyme is the semi-fluid mass of partly digested food that is expelled by the stomach into the duodenum, not a component of gastric juices.
• Amylase: Incorrect. Amylase is an enzyme that breaks down starches into sugars, but it is found in saliva and pancreatic juice, not in gastric juices.
• Glucose: Incorrect. Glucose is a simple sugar that is a product of carbohydrate digestion, not a component of gastric juices.

Summary: Gastric juices are a combination of mucous, pepsinogen, and hydrogen and chloride ions (which form hydrochloric acid).
