- Isoenzymes (also called isozymes) are alternative forms of the same enzyme activity that exist in different proportions in different tissues.
- Isoenzymes differ in amino acid composition and sequence and multimeric quaternary structure; mostly, but not always, they have similar (conserved) structures.

Explanation:
Isoenzymes:
Isoenzymes are different forms of an enzyme that catalyze the same reaction but have different amino acid sequences. They can be separated based on their electrophoretic mobility due to differences in their charge, size, or shape when subjected to an electric field.
Characteristics of Isoenzymes:
- Isoenzymes are encoded by different genes but catalyze the same reaction.
- They may have different kinetic properties, substrate affinities, or regulatory mechanisms.
- Isoenzymes can be tissue-specific or developmentally regulated, serving different physiological functions in different tissues or stages of development.
Significance of Isoenzymes:
- Isoenzymes play a crucial role in cellular metabolism and adaptation to different environmental conditions.
- They can serve as diagnostic markers for specific diseases or tissue damage.
- Studying isoenzyme patterns can provide insights into evolutionary relationships and genetic diversity within a species.
Conclusion:
In the given scenario, the two fractions separated from the enzyme extract are likely to be isoenzymes since they catalyze the same reaction but have different properties. This separation allows for the study of their individual characteristics and functions, contributing to a better understanding of enzyme regulation and cellular processes.
