Using the Michaelis-Menten equation competitive inhibition, the Inhibition constant, Ki of the inhibitor is 53.4 μM.
What is the Ki for the inhibitor?The Ki of an inhibitor is known as the inhibition constant.
The inhibition is a competitive inhibition as the Vmax is unchanged but Km changes.
Using the Michaelis-Menten equation for inhibition:
Kma = Km/(1 + [I]/Ki)Making Ki subject of the formula:
Ki = [I]/{(Kma/Km) - 1}where:
Kma is the apparent Km due to inhibitor Km is the Km of the enzyme-catalyzed reaction[I] is the concentration of the inhibitorSolving for Ki:
where
[I] = 26.7 μM
Km = 1.0
Kma = (150% × 1 ) + 1 = 2.5
Ki = 26.7 μM/{(2.5/1) - 1)
Ki = 53.4 μM
Therefore, the Inhibition constant, Ki of the inhibitor is 53.4 μM.

Describe the Principle of Continuity of State
If any liquid is flowing in a pipe of cross-section area, then rate of flow of liquid across any cross-section remains constant.
Principle of Continuity of StateAccording to the equation of continuity states that if any liquid is flowing in streamline flow in a pipe of non-uniform cross-section area, then rate of flow of liquid across any cross-section remains constant. In the Principle of Continuity of State, Av = constant.
Where A refers to cross-sectional area and v is the velocity in which the fluid flows. It means

How to polymers work?
Answer:
A polymer is any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, which are multiples of simpler chemical units. Polymers make up many of the materials in living organisms and are the basis of many minerals.
Explanation:
Explanation:
The first man-made polymers were actually modified versions of these natural polymers. Celluloid, the stuff from which silent-movie film was made, was a plastic created from chemically modified cellulose. The first completely synthetic polymer (that is, made by people through chemical synthesis), invented in the early years of the twentieth century, was Bakelite: a plastic made by reacting phenol and formaldehyde under pressure at high temperatures.

Water (2470 g ) is heated until it just begins to boil. If the water absorbs 5.47x105 J of heat in the process,
what was the initial temperature of the water?
Express your answer with the appropriate units.
Answer:
47.01 °C
Explanation:
Q = mcΔt
Mass of water = 2470g
c or specific heat capacity of water = 4.18 J °C g
Q = 5.47 x 10⁵ J, which is expanded 547,000 J
No idea what Δt is, but we do know the water began to boil, and we know that water's boiling point is 100°C, so the final temperature had to be 100°C.
547,000 J = (2470) x (4.18) x (Δt)
Rearrange equation for Δt
(547,000) / (2470 x 4.18) = Δt
Δt = 52.98°C
But we're not done. We're trying to find the INITIAL TEMPERATURE of the water, not the TEMPERATURE CHANGE. We already have the final temperature, which is 100°C, and now we have how much the initial temperature rose by to get to 100°C.
All that we have to do now is 100 - 52.98 = 47.02°C
The initial temperature of the water is 47.02°C
How many atoms are in 1mg of NaCl
The number of atoms in 1 mg of NaCl = 1 × 10^19 atoms
Calculation of quantity of atomsAtomic mass of Na = 23
Atomic mass of Cl = 35.5
Therefore the molar mass of NaCl = 23 + 35.5 = 58.5g/mol
But 1 mg = 0.001g and 1 mol = 6.022 × 10^ 23
Therefore, If = 58.5g = 6.022 × 10^ 23 atoms
0.001g =X atoms
X atoms = 6.022 × 10^23 × 0.001/58.5
= 0.1 × 10^23 × 10^-³
= 1 × 10^19 atoms
Therefore, the number of atoms in 1 mg of NaCl =1 × 10^19 atoms.
