Question

Urea is produced in kidneys.
A.True
B.False

Answer 1

Hint: Urea is predominantly found in urine and animal waste which is a natural product of nitrogen and protein metabolism. It is the organic compound which is artificially synthesized from inorganic compounds(starting materials).

Complete answer:
Urea is a colorless, odorless solid, non-toxic, and highly soluble in water. The urea cycle is also known as the Ornithine cycle is a biochemical reaction cycle that produces Urea. It takes place in the liver and extends in kidneys. All organisms want to excrete ammonia waste which is produced by amino acid catabolism. Most of the animals excrete that without converting it. But some organisms remove by converting it into urea, which occurs mainly in the liver through the urea cycle.

Hence the correct answer is OPTION(B)

Note: From a healthy adult, about 10 to 20 grams of ammonia are removed every day. So dysfunction of the urea cycle can mean excess ammonia in the body, which leads to diseases like hyperammonemia , etc. Even 1 mm of excess ammonia can cause damage to the body.
