How do enzymes catalyze chemical reactions (don't just say "they lower the activation energy", give me specific mechanisms)?

They do lower the activation energy but they provide an alternate pathway for the reaction to happen quicker and they do not get used up in the reaction

A protein isolated from a thermophilic bacterium shows a molecular weight of 160 kD when eluted from a size-exclusion chromatogr
Amiraneli [1.4K]

Answer:

as a dimer consisting of two identical monomers (80 kDa subunits) that are packed together via hydrophobic interactions

Explanation:

SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is an electrophoretic methodology used to separate proteins that have a molecular weight between 5 to 250 kDa. SDS is a well-known ionic detergent that is able to break hydrophobic interactions and hydrogen bonds. Moreover, size-exclusion chromatography is a filtration technique that separates molecules in solution according to their molecular size. In this case, SDS-PAGE showed that the target protein is composed of two identical subunits (monomers) of 80 kDa each, which were separated by the detergent and formed one single band in the SDS-PAGE gel.

We are reacting two molecules of nitrogen gas with six molecules of hydrogen gas to form ammonia, nh3
pentagon [3]

To form ammonia, we can react 2 molecules of N₂ with 6 molecules of H₂. Once the reaction has completed, the total molecules of each gas will be: 1 molecule of nitrogen, 3 molecules of hydrogen, and 4 molecules of ammonia.

<h3>How to predict the total molecules of reactants and products?</h3>

The formation reaction of ammonia needs one molecule of nitrogen and 3 molecules of hydrogen. The reaction is as shown in the equation below:

N2(g) + 3H2(g) --> 2NH3(g)

2N2(g) + 6H2(g) --> 4NH3(g)

They will form a new product as four molecules of NH₃. Speaking in the present time after the reaction has completed, half of the reactants (N₂ and 3H₂) are gone to form the ammonia. Hence, the correct answer is: 1 N₂, 3 H₂, and 4 NH₃.


This question seems incomplete. The complete query is as follows:

"We are reacting two molecules of nitrogen gas with six molecules of hydrogen gas to form ammonia, NH₃. How many molecules of each type of gas will be present once the reaction has completed?"
