Answer to Question 1

Correct Answer: 2
Rationale 1: The lungs do not synthesize angiotensinogen.
Rationale 2: The liver synthesizes the protein angiotensinogen.
Rationale 3: The gallbladder does not synthesize angiotensinogen.
Rationale 4: The kidneys do not synthesize angiotensinogen.
Global Rationale: The liver synthesizes the protein angiotensinogen. The lungs, the liver, and the gallbladder do not synthesize angiotensinogen.

Answer to Question 2

Correct Answer: 4
Rationale 1: Fibrogen does not cause vasoconstriction.
Rationale 2: Sodium is not a peptide.
Rationale 3: Kinase is not a peptide.
Rationale 4: Angiotensin is a peptide that causes vasoconstriction.
Global Rationale: Angiotensin is a peptide that causes vasoconstriction. Fibrogen does not cause vasoconstriction. Sodium and kinase are not peptides.
