AST activity decreases more rapidly than CK activity after muscle injury. A) True B) False

Understand the Problem

The question is asking to verify whether it is true or false that AST activity decreases more rapidly than CK activity following a muscle injury.

More Information

AST activity rises more slowly following damage to muscle cell membranes than CK activity. Therefore, CK activity decreases more rapidly than AST activity after muscle injury.

Tips

A common mistake is misunderstanding the half-life of these enzymes and their peak times post-injury.
