Digestive System
1. The first chemical digestion of proteins takes place in _______.
- A. Mouth
- B. Oesophagus
- C. Stomach
- D. Intestine
View answer and explanation
Answer: C. Stomach
Chemical digestion of proteins begins in the stomach, where hydrochloric acid denatures proteins and activates pepsinogen into pepsin, which breaks proteins into peptides. No protein digestion occurs in the mouth or oesophagus, and the intestine only continues the process. Thus the first chemical digestion of proteins takes place in the stomach, so C is correct.
Digestive System
2. The structure that directly receives secretions from the liver and pancreas is the:
- A. Stomach
- B. Ileum
- C. Duodenum
- D. Gallbladder
View answer and explanation
Answer: C. Duodenum
Keyword/Clue: directly receives secretions from the liver and pancreas Concept/Formula: The duodenum receives bile (liver secretion) and pancreatic juice through ducts that open into it (hepatopancreatic ampulla/major duodenal papilla). Why the Other Options Are Wrong: - Option A: The stomach does not directly receive bile and pancreatic secretions; they enter the small intestine. - Option B: The ileum is distal small intestine; bile and pancreatic ducts open into the duodenum, not the ileum. - Option D: The gallbladder stores and concentrates bile; it does not receive pancreatic secretions and does not serve as the entry point into the intestine.
Digestive System
3. Chief (zymogenic) cells in the stomach secrete which inactive enzyme?
- A. Mucus
- B. Trypsinogen
- C. Gastrin
- D. Pepsinogen
View answer and explanation
Answer: D. Pepsinogen
Chief cells secrete pepsinogen, which is the inactive precursor to the protein-digesting enzyme pepsin.
