Which of the following statements is incorrect?
Which of the following statements is incorrect?
Show Hint
Remember the blood clotting conversion sequence as:
Fibrinogen (soluble) $\rightarrow$ Fibrin (insoluble clot fibers).
If reversed in options, it is incorrect.
Updated On: Jun 21, 2026
- Fibrinogen is produced from fibrin
- Blood coagulates in response to an injury
- Blood clot consists of fibrins
- Fibrin is produced from fibrinogen
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Recall the clotting idea.
Blood clotting is a protective response that stops bleeding after an injury. We must spot the one wrong statement.
Step 2: Know the precursor and product.
Fibrinogen is a soluble plasma protein. The enzyme thrombin converts it into insoluble fibrin. So the direction is fibrinogen to fibrin.
Step 3: Test option 1.
It says fibrinogen is produced from fibrin. This reverses the real pathway, so this statement is incorrect, which is exactly what the question asks for.
Step 4: Test option 2.
Blood coagulates in response to an injury. This is correct, since clotting is a defence triggered by vessel damage.
Step 5: Test option 3.
A blood clot consists of fibrins. Correct, because fibrin threads form the mesh of the clot.
Step 6: Test option 4 and conclude.
Fibrin is produced from fibrinogen. This is correct. Hence the only incorrect statement is option 1.
\[ \boxed{\text{Fibrinogen is produced from fibrin}} \]
