The covalent catalytic mechanism of an enzyme depends on a single active site Cys whose pK is 8. A mutation in a nearby residue
Nimfa-mama [501]

Answer: The reaction rate will INCREASE

Explanation: enzymes are not consumed by the reaction they catalyse, enzyme assay usually follow changes in the concentration of substrate or product to measure the rate of reaction. Now the cys active site contains thiolate ion which will increase on increase of the pk from 8 to 10. Hence increasing the rate of reaction which is catalysed by the active form of the enzyme.

If the pressure on an ideal gas is increased, what will happen to the volume of the gas?
kumpel [21]
If the pressure on an ideal gas is increased, the volume of the gas will decrease. This can be predicted with the use of the ideal gas equation which is expressed as: PV = nRT. At constant temperature, we can say that pressure and volume are inversely related. Thus, as one value increase, the other decrease.

Suppose the concentration of the standard stock solution is 50.04 ppm and that you delivered 4.60 mL of this standard stock solu
12345 [234]

Answer:

9.21 ppm

Explanation:

Considering

concentration_{working\ solution}\times Volume_{working\ solution}=concentration_{stock\ solution}\times Volume_{stock\ solution}

Given  that:

concentration_{working\ solution}=?

Volume_{working\ solution}=25.00mL

Volume_{stock\ solution}=4.60mL

concentration_{stock\ solution}=50.04 ppm

So,  

concentration_{working\ solution}\times 25.00mL=50.04 ppm\times 4.60mL

concentration_{working\ solution}=\frac{50.04\times 4.60}{25.00}\ ppm=9.21\ ppm

Stars composed of heavier (more massive) elements are often slightly older than stars made predominantly from hydrogen and heliu
g100num [7]

Answer:

Newly discovered star is a younger star

Explanation:

The composition of the newly discovered star is Hydrogen, Lithium, Neon, Sodium, Mercury

It consists of both hydrogen and helium of which the old stars are not made up of as they are heavier than the new stars.

Considering the above fact, it can be stated that the new star is a young star.
