Absence of angiotensin converting enzyme will lead to decreased blood pressure increased blood pressure will not have any effect on blood pressure all of these choices are correct. none of these choices is correct.

Decreased blood pressure

Angiotensin II is a hormone and its effect on the body is that of vasoconstriction. Vasoconstriction is when the blood vessels within the body constrict, increasing the blood pressure in the body. However, angiotensin is present in the body as angiotensin I, which is the precursor to angiotensin II and has to be converted in the body. If the enzymes necessary to do so are absent, angiotensin II will not be produced and the blood pressure of the body will not be elevated.
