Answer:
C)LDH
Explanation:
LDH, or lactate dehydrogenase, is an enzyme present in various body tissues, including the heart. In instances of cellular damage, such as during a heart attack, LDH is released into the bloodstream. Therefore, monitoring LDH levels in the blood can provide insights into cellular damage, including damage to the heart muscle. Unlike GPT (A), lipase (B), and lysozyme (D), LDH specifically indicates such cardiac issues and is commonly used for this purpose.
The enzyme valuable in diagnosing heart attacks from the provided options is LDH. It's used as an indicator of heart damage. Caseinase is an extracellular protease that breaks down the protein casein. Thus the correct option is option C) LDH.
An enzyme valuable in diagnosing heart attacks is Lactate dehydrogenase (LDH). Among the options given, LDH (C) is the correct answer because during a heart attack, the increased level of the LDH1 isoenzyme is used as an indicator of myocardial infarction (heart damage). Creatine phosphokinase (CPK) is another enzyme that is a marker for such diagnoses due to its rapid increase in the blood plasma after a heart attack. However, it is not listed as one of the answer options in the question provided.
The second question asking about the type of enzyme caseinase is concerns. Among the options, extracellular protease (C) is the correct answer since caseinase is indeed an enzyme that breaks down the milk protein casein outside of cells.
