Question

Which option is correct for the formation of intrinsic factor-X activator complex for blood coagulation?

• A. Activated Christmas factor + AHG + phospholipid + $C{a}^{+2}$
• B. Inactivated Christmas factor + AHG + phospholipid +$C{a}^{+2}$
• C. Convertin + AHG + $C{a}^{+2}$+ FSF
• D. Phospholipid - protein complex + Proconvertin

Answer 1

The correct option is A Activated Christmas factor + AHG + phospholipid + $C{a}^{+2}$

The Hageman factor XII is activated when it comes in contact with a damaged blood vessel. The activated Hageman factor activates the factor XI. The activated factor XI acts on Chrishmas factor IX to form activated IXa. Factor IXa combines with AHG VIII phospholipid and calcium ions to form a complex called intrinsic factor X activator complex. Thus the correct answer is option A.
