Answer #1

Competitive regulation of an enzyme suggests that _substrate levels are around or below active site saturating levels in the cells in which this enzyme operates.

Hope so these options are correct. Correct explanation for this inhibition is explained below.

Competitive regulation, inhibitor resembles with substrate known as substrate analogue. This inhibitor compete with substrate to bind at active site. So due to competition between substrate and inhibitor fifth bonding at active site , leads to increased km.

While this inhibition can be reversed by increasing substrate concentration. So Vmax remain unchanged

So in competitive regulation- km decreased, Vmax unchanged
