What would change if the lungs did not produce Angiotensin-Converting Enzyme?

What is/are the differences between the two sphincters of the urinary bladder? (Can you make a chart for this one :) )

Thanks so much <3

Answer

1)

Angiotensin-Converting Enzyme (ACE) converts angiotensin-I into angiotensin-II.
Angiotensin-II is a vasoconstrictor. It also stimulates aldosterone release from adrenal cortex.
If lungs did not produce Angiotensin-Converting Enzyme, this conversion will not occur.
Unavailability of angiotensin-II will prevent vasoconstriction and in turn prevents increase in blood pressure. Also deficiency of aldosterone will lead to excess loss of sodium in urine.
Collectively, there will be increased loss of sodium and water as well as decreased blood pressure below normal.

2)

The two sphincters that allows emptying of urine from urinary bladder are urethral sphincters.

Enalaprilat is a competitive inhibitor of the angiotensin-converting enzyme (ACEACE), which cleaves the blood-pressure regulating peptide angiotensin I. ACEACE has a KM=52KM=52 μMμM for angiotensin I, which is present in plasma at a concentration of 78 μMμM. When enalaprilat is present at 2.8 nMnM, the activity of ACE in plasma is 13 %% of its uninhibited activity. What is the value of KIKI for enalaprilat?
