Which group of cells in the kidneys makes up the apparatus that helps control renin secretion?
 
  1. The red blood cells and slit pores
  2. The nephron and Bowman's capsule
  3. The juxtaglomerular (JG) cells and the macula densa
  4. The tubular and the glomerulus

Question 2

The angiotensin-converting enzyme (ACE) converts angiotensin I almost instantly to which substance?
 
  1. Angiotensin II
  2. Aldosterone
  3. Angiotensinogen
  4. Renin

Answer to Question 1

Correct Answer: 3
Rationale 1: The red blood cells and the slit pores do not help control renin secretion in the kidneys.
Rationale 2: The nephron and Bowman's capsule do not help control renin secretion.
Rationale 3: The JG cells and the macula densa are the cells that help control renin secretion.
Rationale 4: The tubular and glomerulus of the kidneys do not help control renin secretion.
Global Rationale: The JG cells and the macula densa are the cells that help control renin secretion. The red blood cells and the slit pores do not help control renin secretion in the kidneys. The nephron and Bowman's capsule do not help control renin secretion. The tubular and glomerulus of the kidneys do not help control renin secretion.

Answer to Question 2

Correct Answer: 1
Rationale 1: ACE converts angiotensin I to angiotensin II. This happens almost immediately because ACE lies on the membranes of the blood vessels.
Rationale 2: ACE does not convert angiotensin I to aldosterone.
Rationale 3: ACE does not convert angiotensin I to angiotensinogen.
Rationale 4: ACE does not convert angiotensin I to renin.
Global Rationale: ACE converts angiotensin I to angiotensin II. This happens almost immediately because ACE lies on the membranes of the blood vessels. ACE does not convert angiotensin I to aldosterone, angiotensinogen, or renin.
