In Ornithine cycle, which of the following wastes are removed from the blood ?
Urea and urine
Ammonia and urea
CO2 and ammonia
CO2 and urea
The Correct Option is C
Solution and Explanation
The Ornithine cycle, primarily taking place in the liver, is responsible for eliminating two waste products, namely Ammonia (NH3) and Carbon dioxide (CO2), from the bloodstream. Within the liver, specific molecules and enzymes interact with carbon dioxide and ammonia, converting them into urea. This process is commonly referred to as the urea cycle. In each cycle of this process, two ammonia molecules and one carbon dioxide molecule are converted into urea.
So, the correct option is (C): CO2 and ammonia

Concepts Used:
Mechanism Human Excretory System
Excretory System Organs
Kidneys- Kidneys are bean-shaped structures located on either side of the backbone. In human each adult kidney size is 10-12 cm with a width of 5-7 cm and weighs around 120-170g and it have an inner concave structure.
Ureter - A pair of thin muscular tubes called the ureter. Ureter comes out of each kidney extending from the renal pelvis and it carries urine from the kidney to the urinary bladder.
Urinary Bladder - muscular sac-like structure which stores urine. The urinary bladder is emptied by the process of micturition.
Urethra- This tube comes out from the urinary bladder and helps to expel urine out of the body. It acts as the common route for sperms and urine in males.
