Deamination occur in

  1. Kidney

  2. Liver

  3. Nephron

  4. Both 1 and 2

Deamination is the process of removal of amino acids like serine and threonine from molecules and the enzyme that catalyses the reaction is deaminases. In the human body, it takes place primarily in the liver however glutamate is also deaminated in the kidneys.

So, the correct answer is 'both 1 and 2'.

  2. Kidney

  3. Stomach

  4. Small intestine
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Hormones are secreted by the endocrine glands which are specific in nature.
  • Each hormone causes a response in a target organ or tissues.
  • Once the function of the hormones is completed on their target organs or tissues they are destroyed. 
  • They are destroyed by the liver or the tissues of the target organs. 
  • The destroyed hormone is removed by the kidney. 
  • So, the correct answer is 'Liver'.

If $A=$ hepatic duct, $B=$common bile duct, $C=$hepato-pancreatic duct and $D=$cystic duct, then which of the following will not be having concentrated bile juice?

  1. A

  2. B

  3. C

  4. D
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Bile is produced in the liver and then it's concentrated in the gallbladder. From gallbladder, it goes through the cystic duct. Cystic duct joins the pancreatic duct to form the hepato-pancreatic duct. Pancreatic juice and bile juice together is secreted through a common hepatic duct into the duodenum. During secretion from the hepato-pancreatic duct, pancreatic juice is present too making bile juice diluted. 

So, the correct option is 'C'.

Which of the following blood proteins (clotting factors) are produced by liver?

  1. Thrombin and prothrombin

  2. Anti hemophilic and fibrinogen

  3. Prothrombin and Fibrinogen

  4. Thromboplastin and thrombin
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The liver synthesizes most of the major plasma proteins involved in blood coagulation, notably prothrombin and fibrinogen. Other factors like thrombin are active enzymes converted in the blood rather than directly synthesized as active factors by the liver.

Liver excretes?

  1. Urea

  2. Uric acid

  3. Bile pigments

  4. Albumin
Reveal answer Fill a bubble to check yourself
C Correct answer
