Assertion is correct,but Reason is incorrect.

Vedclass · Answer

(C) Assertion: $\alpha$-amylase in wheat endosperm is known to exist in multiple isoenzymic forms,specifically $16$ isoenzymes,which help in the mobilization of starch during germination.Reason: In competitive inhibition,the inhibitor resembles the substrate and competes for the active site. This increases the $K_m$ value,but the $V_{max}$ remains unchanged because the inhibition can be overcome by increasing the substrate concentration. Therefore,the statement that $V_{max}$ decreases is incorrect.

$A$ : $\alpha$-amylase of wheat endosperm has $16$ isoenzymes.
$R$ : In competitive inhibition,$V_{max}$ decreases.
