Worked Example: Isozymes For CSIR NET Question with Solution
Isozymes, also known as isoenzymes, are different forms of an enzyme that catalyze the same chemical reaction. They differ in their amino acid sequences, and often in their regulatory properties. A classic example of isozymes is the enzyme lactate dehydrogenase (LDH), which exists in five different isoforms. Isozymes For CSIR NET requires understanding of such examples.
A student of biochemistry is investigating the kinetics of LDH isozymes. The student has purified two isoforms of LDH, LDH-1 and LDH-5, and is comparing their kinetic properties. The Michaelis-Menten constants (Km) for the two isoforms are:
| Isoform | Km(mM) |
|---|---|
| LDH-1 | 0.5 |
| LDH-5 | 2.0 |
Which of the two LDH isozymes has a higher affinity for its substrate? Explain.Solution:The isozyme with the lower Km value has a higher affinity for its substrate. Therefore, LDH-1 has a higher affinity for its substrate than LDH-5. This difference in kinetic properties allows the cell to regulate enzyme activity in response to changing conditions, illustrating the significance of isozymes in enzyme kinetics and their role in understanding enzyme regulation and adaptation to environmental changes for topics like Isozymes For CSIR NET.
Common Misconceptions About Isozymes For CSIR NET
Many students assume that isozymes and isoenzymes are interchangeable terms, which is incorrect. This misconception arises from a lack of understanding of the distinct meanings of these two terms. In reality,isoenzymes refer to different forms of an enzyme that catalyze the same reaction but differ in their amino acid sequence, structure, or regulatory properties.
