Which Enzyme is Unsuitable as a Marker Enzyme?

[Turkish]

Hey, this is a multiple choice with a explanation as to which enzyme is unsuitable as a marker enzyme, and i actually have no idea!

a. Glutamate dehydrogenase
b. Cytidylyl transferase
c. Succinate dehydrogenase
d. Acid phosphatase
e. Malate dehyrogenase
f. Citrate synthase
g. Glucose-6-phosphatase

perhaps a little explanation would be nice too! thanks!

Do you know where these enzymes are located (specifically-located)? If not, you have some work to do, eh?

I would first consider the role of a marker enzyme in a biological system. A marker enzyme is an enzyme that is used to measure a specific biological process or reaction. Therefore, the most suitable marker enzyme for a particular system would be one that is directly involved in that process or reaction.

Based on this understanding, I would say that the unsuitable market enzyme in this multiple choice question is glucose-6-phosphatase (option g). This is because glucose-6-phosphatase is primarily involved in the conversion of glucose-6-phosphate to glucose, and is not directly involved in any of the other processes or reactions listed in the options.

On the other hand, the other enzymes listed in the options have more specific roles in important biological processes. For example, glutamate dehydrogenase (option a) is involved in the metabolism of amino acids, cytidylyl transferase (option b) is involved in the synthesis of DNA and RNA, succinate dehydrogenase (option c) is involved in the citric acid cycle, acid phosphatase (option d) is involved in the breakdown of phosphates, malate dehydrogenase (option e) is involved in the conversion of malate to oxaloacetate, and citrate synthase (option f) is involved in the first step of the citric acid cycle.

In summary, the most suitable marker enzyme would be one that is directly involved in the specific biological process or reaction being measured. Therefore, glucose-6-phosphatase, which is not directly involved in any of the listed processes, would be the unsuitable marker enzyme in this multiple choice question.
