Question

A person who is on a long hunger strike and is surviving only on water will have

• A. Less amino acids in his urine
• B. More glucose in his blood
• C. Less urea in his urine
• D. More sodium in his urine

Answer 1

The correct option is C Less urea in his urine

Urea is a nitrogenous compound produced by the metabolism of proteins. The protein metabolism produces urea in liver in ornithine cycle. The urea is filtered in kidneys to form urine. As protein intake is zero in case of prolonged fasting and surviving only on water, urea will not be produced in the body. Thus, the correct answer is option C.
