What is the 2nd arm of hemostasis?


✓ The coagulation cascade




How many coagulation factors are there?


✓ 12




What are the coagulation factors made of?


✓ They are plasma proteins; most produced in the liver




How are the coagulation factors named?

✓ In order of discovery.




What are coagulation factors in an inactive form?


✓ Zymogens




How is an activated zymogen noted as?


✓ With a after factor roman numeral (ex. Va is activated factor V).




What is considered the primary pathway of coagulation?


✓ Extrinsic pathway




When is the extrinsic pathway activated?


✓ When Tissue Factor is exposed at the site of injury




What is the process of the extrinsic pathway?

, 1 | P a g e | © copyright 2024/2025 | Grade A+

✓ Tissue Factor (III) exposed; binds with VII to form TF/VIIa complex;

TF/VIIa activates X-Xa; Xa binds with Va and calcium to form

prothrombinase complex; prothrombinase complex converts factor II

(prothrombin) to IIa (thrombin); IIa then activates 4 factors (I -

fibrinogen to Ia - fibrin; factors V, VIII and XIII); fibrin (Ia) placed over

platelet plug and XIIIa stabilizes the fibrin




Does a deficiency in factor XII (Hageman factor) cause bleeding?


✓ No




What is the main function of the intrinsic pathway?


✓ To enhance the extrinsic pathway




When is the intrinsic pathway activated?


✓ When the blood is exposed to negative charges which are found on

the molecules of ADP and ATP.




What is the process of the intrinsic pathway?


✓ Exposure activates XII (Hageman factor); XIIa then activates XI; XIa

activates IX; IXa then activates X; XA then forms the prothrombinase

complex in the common pathway

What must vitamin K dependent coagulation factors undergo in order to be a

functional protein?


✓ The process of carboxylation




When does carboxylation occur?


✓ Prior to the time a factor would be activated and is essentially part of

the maturation of the protein




What happens if vitamin K dependent coagulation factors do not undergo

carboxylation?


✓ They will not be functional proteins and cannot participate in the

coagulation process.




What is carboxylation?


✓ The change of glutamate to y-carboxygluatmate (which occurs after

the translation of glutamate) in the vitamin K dependent proteins

involved in the coagulation process.




What are the vitamin K dependent proteins?
