Explanation:
According to the given data, the turnover number can be calculated as follows.
Turnover number =
Therefore, moles of hydrolyzed is as follows.
Moles of hydrolyzed =
=
= 0.00682 moles
Now, moles of hydolyzed per second is calculated as follows.
Moles of hydolyzed per second =
=
And,
Moles of enzyme =
=
= moles
Therefore, the value of is as follows.
= per second
= per minute
= per minute
Thus, we can conclude that the turnover number () of carbonic anhydrase (in units of
) is
per minute.
