Question 1

What is the most suitable biomarker for identifying cardiac muscle damage?

Answer 1

Troponin

Question 2

True or False: Creatine kinase (CK) is a more specific biomarker for cardiac muscle damage than troponin.

Answer 2

False

Question 3

Fill in the blank: Troponin is a protein complex involved in the regulation of __________ in cardiac muscle.

Answer 3

muscle contraction

Question 4

What are the two main types of troponin used as biomarkers for cardiac injury?

Answer 4

Troponin I (TnI) and Troponin T (TnT)

Question 5

How does troponin levels change in response to cardiac muscle damage?

Answer 5

Troponin levels increase in the bloodstream following myocardial injury.

Question 6

Which enzyme is often compared to troponin for assessing cardiac damage?

Answer 6

Creatine kinase (CK-MB)

Question 7

True or False: Troponin can remain elevated for several days after a cardiac event.

Answer 7

True

Question 8

What is the biochemical basis for the release of troponin into the bloodstream?

Answer 8

Cardiac muscle cell damage leads to the breakdown of cell membranes, releasing troponin into circulation.

Question 9

Multiple Choice: Which of the following is NOT a reason troponin is preferred over other biomarkers? A) High specificity B) Quick clearance C) Sensitivity to minor damage

Answer 9

B) Quick clearance

Question 10

What is the clinical significance of measuring troponin levels in patients?

Answer 10

It helps in diagnosing acute myocardial infarction and assessing the extent of myocardial injury.
