Enzymes often play a significant role in medications used to treat a variety of ailments. For example, hypertension can be treated effectively with medications, such as Captopril, that are angiotensin converting enzyme (ACE) inhibitors. Antigen converting enzymes convert Angiotensin I to Angiotensin II in the blood stream. What is Angiotensin I and how does it affect blood pressure (1 pt)? What is Angiotensin II and how does it affect blood pressure (1 pt)? How do antigen converting enzymes increase blood pressure (1.5 pt)? How do antigen converting enzyme inhibitors (ACE inhibitors), such as Captopril lower blood pressure (1.5 pt)? Specifically, what enzymatic pathways are affected by ACE inhibitors and how are they affected?
