Question

multiple choice question
which statement about clotting factors is true?

they are also known as anticoagulants.

they are identified by roman numerals which indicate the order of the reactions.

clotting factors initiate a cascade of reactions.

most are produced in the spleen.

Explanation:

1. Analyze "They are also known as anticoagulants": Clotting factors promote clotting, while anticoagulants prevent it. So this is false.
2. Analyze "They are identified by roman numerals which indicate the order of the reactions": Clotting factors are numbered with Roman numerals, but the numbering doesn't represent the reaction order. So this is false.
3. Analyze "Clotting factors initiate a cascade of reactions": The coagulation process is a cascade where one clotting factor activates another, so this is true.
4. Analyze "Most are produced in the spleen": Most clotting factors are produced in the liver, not the spleen. So this is false.

Answer:

Clotting factors initiate a cascade of reactions.
