Which of the following statements regarding enzymes is FALSE? a. Enzymes alter the free energy change (ΔG) of the reactions whic
const2013 [10]

Answer:

Enzyme function is dependent on the three-dimensional structure or conformation of the enzyme

Explanation:

Enzyme are biological catalysts.

So they do alter the path of the reaction where the free energy change (or activation energy) is low then the non enzymatic pathway.

Thus the statement

Enzymes alter the free energy change (ΔG) of the reactions which they catalyze : True

It is known that for enzyme we function they need an optimum temperature and pH condition so the statement

Enzyme function is dependent on the pH and temperature of the reaction environment: true

This is also true that

Enzyme activity can be inhibited if the enzyme is bound by a noncompetitive inhibitor.

The false statement is : Enzyme function is dependent on the three-dimensional structure or conformation of the enzyme

Determine the molality of an aqueous solution that is 16.5 percent urea by mass
yarga [219]

Take a hypothetical sample of exactly 100 grams of the solution.  

(16g urea) / (60.06 g urea/mol) = 0.2664 mol urea  

((100 g total) - (16g urea)) = 84.0 g H2O = 0.0840 kg H2O  

(0.2664  mol) /0.0840  (kg) = 3.17143mol/kg = 3.18m urea
