Enzymes from the same organism which catalyze same reaction but are chemically and physically distinct from each other are called______________?
Correct answer: C. Isoenzymes
- A. Oxidoreductases
- B. Hydrolases
- C. Isoenzymes
- D. Isomerases
Explanation
Isoenzymes are different molecular forms of an enzyme found in the same organism that catalyse the same reaction but differ in physical and chemical properties. Hydrolases are an enzyme class based on reaction type, so choosing them misses the significance of the enzymes being distinct forms.

About Enzymes as Biocatalysts
Enzymes are protein or RNA biocatalysts that lower activation energy without being consumed, and their active sites bind specific substrates. The topic covers the lock and key and induced fit models, effects of temperature, pH and substrate concentration, cofactors, enzyme specificity, and competitive versus non-competitive inhibition.
