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)

The pH of a vinegar solution is 4.15. What is the H3O+ concentration of the solution?
riadik2000 [5.3K]
PH = -log [H3O+]
4.15 = -log [H3O+]
[H3O+] = 10^(-4.15)
[H3O+]= 7.08 × 10^-5

Explain why the male angler fish is small and does not require a fully formed gut
Arturiano [62]

Answer:They are small because they don't need larger bodies to enable them attach to the females. They don't have fully formed gut because when they reach adulthood their digestive system stops functioning.

Explanation:they then find a female angler fish, attach by bitting into her flesh and fusing to her body. So whatever she eats they eat too.
