Answer:

It is divisible!

Explanation:

Dalton stated that an atom was indivisible but was later proven wrong when subatomic particles protons, neutrons, and electrons were discovered.

The protein catalase catalyzes the reaction The Malcolm Baldrige National Quality Award aims to:
Marina CMI [18]

The question is missing a part, so the complete question is as follows:

The protein catalase catalyzes the reaction The Malcolm Bladrigde National Quality Awards aims to: 2H2O2 (aq) ⟶ 2H2O (l) + O2 (g) and has a Michaelis-Menten constant of KM = 25mM and a turnover number of 4.0 × 10 7 s -1. The total enzyme concentration is 0.012 μM and the intial substrate concentration is 5.14 μM. Catalase has a single active site. Calculate the value of Rmax (often written as Vmax) for this enzyme. Calculate the initial rate, R (often written as V0), of this reaction.

1) Calculate Rmax

The turnover number (Kcat) is a ratio of how many molecules of substrate can be converted into product per catalytic site of a given concentration of enzyme per unit of time:

Kcat = \frac{Vmax}{Et},

where:

Vmax is maximum rate of reaction when all the enzyme sites are saturated with substrate

Et is total enzyme concentration or concentration of total enzyme catalytic sites.

Calculating:

Kcat = \frac{Vmax}{Et}

Vmax = Kcat · Et

Vmax = 4×10^{7} · 1.2 × 10^{-8}

Vmax = 4.8 × 10^{-1} M

2) Calculate the initial rate of this reaction (R):

The Michaelis-Menten equation studies the dynamics of an enzymatic reaction. This model can explain how an enzyme enhances the rate of a reaction and how the reaction rate depends on the concentration of the enzyme and its substrate. The equation is:

V0 = \frac{[S].(Vmax)}{KM + [S]}, where:

[S] is the substrate's concentration

KM is the Michaelis-Menten constant

Substituting [S] = 5.14 × 10^{-6}, KM = 2.5 × 10^{-4} and Vmax = 4.8 × 10^{-1}, the result is V0 = 0.478 M.

The answers are Vmax = 4.8 × 10^{-1} M and V0 = 0.478 M.

Why are soluble ionic compounds such as mgcl2 electrolytes? choose one: the compound contains a metal, and metals are conductors
lawyer [7]
<h3><u>Answer;</u></h3>

the ions dissociate from each other in solution and are free to move independently

<h3><u>Explanation;</u></h3>
  • <em><u>All soluble ionic compounds are strong electrolytes. They conduct very well because they provide a plentiful supply of ions in solution. That is;  they mostly break up into ions as they dissolve in water</u></em>.
  • An electrolyte solution conducts electricity because of the movement of ions in the solution.
  • Ionic compounds have ions that are electrically charged to conduct electricity in liquid state or in aqueous solutions.
