CK-BB is primarily associated with which tissue type?

Explanation:
Creatine kinase has tissue-specific isoenzymes, and CK-BB is the brain-type. It is predominantly found in brain tissue, so it is the best match for this question. In contrast, CK-MB is the heart-type isoenzyme and CK-MM is the skeletal muscle type, which is why they’re linked to those tissues rather than the brain. CK-BB can be elevated in cases of brain injury or stroke, whereas the other isoenzymes are more relevant to their respective tissues. Liver isn’t the primary source of CK-BB.
