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

Hydrocarbons containing a saturated carbon ring are called _____.
lisabon 2012 [21]

Answer : The hydrocarbons containing a saturated carbon ring are called Aliphatic cyclic hydrocarbon.

Explanation :

As the organic compounds are classified into two categories that is acyclic (aliphatic) and cyclic (aromatic) compounds.

Acyclic compounds : It is an open chain compound with linear structure.

Cyclic compounds : It is a closed chain compound having a carbon ring structure.

Hydrocarbon : It is an organic compound that contains only hydrogen and the carbon atoms. They are of two types which are saturated hydrocarbon and unsaturated hydrocarbon.

Saturated hydrocarbon : These are the compounds which containing single bonds between the carbon-carbon atoms. In saturated compounds, there are more number of hydrogen bonded with the carbon atom.

Unsaturated hydrocarbon : These are the compounds which containing double and triple bonds between the carbon-carbon atoms. In unsaturated compounds, there are less number of hydrogen bonded with the carbon atom.

Hence, the hydrocarbons containing a saturated carbon ring are called Aliphatic cyclic hydrocarbon.

Natali5045456 [20]

The density of the rock in g/mL : 14 g/ml

Complete question :

A rock with a mass of 70 grams is dropped into a graduated cylinder with 30 mL of water in it. The water level rose to 35 mL calculate the density of the rock in g/mL

<h3>Further explanation</h3>

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

Density formula:  

\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}

ρ = density  

m = mass  

v = volume  

mass of rock = 70 g

Volume of the rock : 35 - 30 = 5 ml

So the density :

\tt \rho=\dfrac{70}{5}\\\\\rho=14~g/ml
