Question

What are isoenzymes?

Short answer

(1) ${\mathrm{LDH}}_1$ found in heart, kidney.

(2) ${\mathrm{LDH}}_2$found in RBC, heart, brain.

(3) ${\mathrm{LDH}}_3$found in Brain, lungs, WBC.

(4 )${\mathrm{LDH}}_4$found in lung. skeletal muscles.

(5) ${\mathrm{LDH}}_5$found in skeletal muscle, liver.

Step-by-step solution

Introduction 

Isoenzymes are enzymes that have different forms that catalyse the same reaction in different cells or tissues of the body.

Given information 

As an example:

Lactate dehydrogenase has five isoenzymes that catalyse the conversion of lactate to pyrulate.
