Enzyme having different molecular arrangement but similar functions is a/an
Enzyme having different molecular arrangement but similar functions is a/an
Open in App
Solution
The correct option is A Isoenzyme
Multiple forms of an enzyme that catalyzes the same reaction but differ from each other in their amino acid sequence composition, substrate affinity and regulatory properties are described as isoenzymes. Lactic dehydrogenase LDH is the best example for this. LDH which catalyzes the reversible conversion of pyruvate to lactate. There are 5 LDH isoenzymes. Each is a homo or heterotetramer of one or two different types of subunits called H and M. This LDH isoenzyme having the different molecular arrangement but similar functions. So, the correct answer is A
