Penicillin is hydrolyzed and thereby rendered inactive by penicillinase, an enzyme present in some resistant bacteria. The mass
Arisa [49]

Answer:

The turnover number is the maximum substrate quantitiy converted to product per enzyme and per second. It can be calculate as follows:

k_c = \frac{V_{max}}{[E]} with [E] active enzyme concentration.

In this case we have Vmax an data to calculate [E]

moles of E=\frac{10^{-9}g}{29600 g/mol}=3.38*10^{-14}

[E]=\frac{3.38*10^{-14}}{0.01 L}=3.38*10^{-12} M

Now k_c=\frac{6.8*10^-10}{3.38*10^{-12}}=201.28 min^{-1}

it is not like any option.

If we assume that V_{max} have the non usual units of mol L^{-1} min^{-1} and it is 6.8*10^-10 mol min^{-1}

So we need divide by the moles of E (in place of [E])

Now k_c=\frac{6.8*10^-10}{3.38*10^{-14}}=20128 min^{-1} = 335 s{-1}

(pass from min^{-1} to s^{-1} dividing by 60)
