This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Enzyme uses, Subject name: Biochemistry
[{'content': 'Which of the following is a functional plasma enzyme: \nSelect and explain. \nA. LDH, B. Acid phosphatase, C. Prothrombin, D. Amylase', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Functional plasma enzymes are those enzymes which are present in plasma as they have function in plasma. E.g.: Lipoprotein lipase Clotting Factors e.g. Prothrombin Non -functional plasma enzymes do not have function in plasma, they are present inside cells and tissues. E.g.: SGOT is present in liver and hea. For option A , LDH , only one type of LDH i.e. type 2 is functional plasma enzyme. So,Prothrombin>>>LDH because out of 5 isotypes of LDH only type 2 is a functional plasma enzyme. So, prothrombin is a better option to be marked.', 'role': 'assistant'}]
