Elis [28]

Answer:

1.620\times 10^{-3} mol/dm^3 sis the maximum velocity of this reaction.

Explanation:

Michaelis–Menten 's equation:

v=V_{max}\times \frac{[S]}{K_m+[S]}=k_{cat}[E_o]\times \frac{[S]}{K_m+[S]}

V_{max}=k_{cat}[E_o]

v = rate of formation of products =

[S] = Concatenation of substrate

[K_m] = Michaelis constant

V_{max} = Maximum rate achieved

k_{cat} = Catalytic rate of the system

[E_o] = Initial concentration of enzyme

We have :

K_m=0.045 mol/dm^3

v=1.15 mmol/dm^3 s=1.15\times 10^{-3} mol/dm^3 s

[S]=0.110 mol/dm^3

v=V_{max}\times \frac{[S]}{K_m+[S]}

1.15\times 10^{-3} mol/dm^3 s=V_{max}\times \frac{0.110 mol/dm^3}{[(0.045 mol/dm^3)+(0.110 mol/dm^3)]}

V_{max}=\frac{1.15\times 10^{-3} mol/dm^3 s\times [(0.045 mol/dm^3)+(0.110 mol/dm^3)]}{0.110 mol/dm^3}=1.620\times 10^{-3} mol/dm^3 s

1.620\times 10^{-3} mol/dm^3 sis the maximum velocity of this reaction.

What’s the answer????
maks197457 [2]

Answer:

Greater

Greater

Explanation:

The amplitude of a wave is the height of the wave or the vertical displacement of the wave motion. We determine a wave amplitude usually by looking at the graph of the wave.

Amplitude is directly proportional to the energy of a wave. The higher the amplitude of a wave, the more its energy.

Frequency is the number of waves that passes a point at a particular instance of time. It is also directly proportional to the energy carried by a wave. The higher the frequency of a wave, the greater its energy.
