Final answer:
The formula for the conversion of urea to blood urea nitrogen (BUN) is: Urea + Water + Enzyme Urease --> Ammonia + Carbon Dioxide. The conversion of urea to BUN occurs in the liver. BUN levels in the blood are used as an indicator of kidney function.
Step-by-step explanation:
The formula for the conversion of urea to blood urea nitrogen (BUN) is:
Urea + Water + Enzyme Urease --> Ammonia + Carbon Dioxide
The conversion of urea to BUN occurs in the liver, where urea is broken down by the enzyme urease into ammonia and carbon dioxide. The resulting ammonia enters the urea cycle, a series of intermediate steps that ultimately leads to the production of urea. BUN levels in the blood are used as an indicator of kidney function.
