What cellular macromolecules make up the complement pathway?

1 answer:

5 0

The cellular macromolecules that are referred by the description above are the LIPIDS. The complement pathway system is a constituent of the natural immunity and this provides us a natural defense against infection. In the complement pathway of the immune system, the macromolecules that make this up are the lipids.

Use the reaction, which produces ammonia, to answer the question.

zepelin [54]

This problem is providing us with the chemical equation depicting the production of ammonia from nitrogen and hydrogen at equilibrium and asks for the correct change when the concentration of nitrogen is increased. At the end, the answer is the forward reaction would increase to start reducing the concentration of N2.

<h3>Chemical equilibrium</h3>

In chemistry, chemical reactions not always reach a 100-% conversion when reactants get in contact in order to carry out the chemical reaction. Thus, there is a point wherein the concentrations remain the same and is called equilibrium.

In such a way, for this problem, we have the following chemical reaction at equilibrium:

$N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)$

Now, according to the Le Ch.atelier's principle, an increase in the concentration of any species, shifts the equilibrium away from it, which means that if we increase the concentration of nitrogen, a reactant, the forward reaction will be favored.

Thereby, the correct answer is "the forward reaction would increase to start reducing the concentration of N2".

A certain first-order reaction (A→productsA→products) has a rate constant of 9.90×10−3 s−1s−1 at 45 ∘C∘C. How many minutes does

coldgirl [10]

Answer:

4.66667 minutes

Explanation:

Rate constant, k = 9.90×10−3 s−1

Time = ?

Initial concentration, [A]o = 100

Final concentration, [A] = 6.25

The integral rate law for first order reactions is given as;

ln[A] = ln[A]o − kt

kt = ln[A]o - ln[A]

t = ( ln[A]o - ln[A]) / k

t = [ln(100) - ln(6.25)] / 9.90×10−3

t = 2.77 / 9.90×10−3

t = 0.28006 ×103

t = 280 seconds

t = 4.66667 minutes (Upon conversion by dividing by 60)

You have two sealed jars of water at the same temperature. in the first jar there is a large amount of water. in the second jar

n200080 [17]

The vapor pressure of the jar with a large amount of water and the jar with a small amount of water is the same. Vapor pressure is an intrinsic property. This means that this property is not dependent on the amount of the substance. Vapor pressure is dependent only on temperature and since the temperature is the same for both jars, their vapor pressures are also the same.
