Which enzyme is responsible for the conversion of inactive fibrinogens to fibrins? (1) Thrombin (2) Renin (3) Epinephrine (4) Thrombokinase

Correct option:(1)Thrombin
Solution:

  • During coagulation of blood, an enzyme complex thrombokinase helps in the conversion of prothrombin (present in plasma) into thrombin.
  • Thrombin further helps in the conversion of inactive into fibrins which form network of threads.
  • Renin is secreted by JG cells in response to fall in glomerular blood flow.
  • It converts angiotensinogen in blood to angiotensin-I
  • Epinephrine or adrenaline is secreted by adrenal medulla in response to stress of any kind and
    during emergency.
