Isozymes catalyze the same reactions, and have different kn and vmax(t/f)

TRUE

Explanation:

Isozymes are enzymes that differ in amino acid sequence but catalyze the same chemical reaction.  

These enzymes usually have different enzyme kinetics, that is, they have different Km and Vmax values,

For example, three isozymes of lactate dehydrogenase (A, B, and C) have Km values of 0.260, 0.172, and 0.052 mmol/L, respectively.

i would say b

explanation:

but i think i would need more information than that
