Catalysts and Catalysis

Constitutive enzymes are those, which are being synthesized continually, regardless of conditions or demand.

Inductive enzymes are those which are not always present and whose synthesis is activated (or induced - hence the name) by certain molecule or compound, often a hormone or even its own substrate. As example of inductive enzyme serves pyruvate carboxylase (enzyme which turns pyruvate into oxalacetate) which is synthesized on demand and the process is activated by cortisol.

A catalyst reduces the amount of energy required to produce the reaction. This speeds up the reaction and causes it to finish more quickly. Raising the temperature will also speed up a reaction.

The balanced chemical equation for the reaction between ammonium nitrate (NH4NO3) and sodium hydroxide (NaOH) is:
NH4NO3 + NaOH -> NH3 + H2O + NaNO3

First of all what is a biological molecule? Its a group of substances that make up and helps with proper functioning of a living organism.

There are several different types of biological molecules:

- Carbohydrates

- Proteins

- Salts

- Lipids

-etc.

A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.

Assuming the enzyme has been denatured in an environment of variant pH and temperature that has disrupted the R group and backbone bondings a restoration to optimum, for the enzyme, conditions can allow the bonds to reconstitute themselves and the enzyme will return to shape and function. I am not sure if the class of folding assistance proteins, chaperons, are involved in reconstituting denatured proteins.

They have the role of a support for catalysts; I suppose that you think to aluminium oxide.

Manganese dioxide (MnO2) stains on glassware can be easily removed by rinsing with an oxalic acid solution because oxalic acid reacts with MnO2 to form soluble manganese oxalate which can be washed away with water, leaving the glassware clean. Oxalic acid works as a chelating agent, helping to dissolve and remove the manganese dioxide stain effectively.

Manganese dioxide is non-homogeneous catalyst.

Since enzymes, being proteins, do not fit the definition of living organisms, they do not respire. That having been said, enzymes do indeed play a vital role in the process of both aerobic and anaerobic cellular respiration. They are not alive and so do not respire, but respiration could not occur without their help.

A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.

The reactant concentrations decrease

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It lowers the activation energy required for the reaction to occur, thereby speeding up the reaction. Catalysts remain unchanged at the end of the reaction and can be used multiple times.

The answer is rest

Enzyme will reduce the activation energy of the reaction, thereby the speed of the reaction increases or acting as a catalyst.

A catalyst in cooking is a substance that increases the rate of a chemical reaction without being consumed in the process. In food preparation, catalysts are often enzymes present in ingredients that help break down complex molecules into simpler compounds, aiding in processes like fermentation or tenderizing meat. They can also refer to ingredients or techniques that accelerate reactions, such as using acidic ingredients like vinegar or lemon juice to speed up curing or marinating.

Neither. Once they are dried the wood is the most flammable component. According to the National Paint and Coatings Association, conventional paints and

coatings do not increase the flame spread of either non-flammable or flammable substrates upon which they are applied.

The first biological catalyst that originated on Earth is believed to be RNA (ribonucleic acid). RNA can act as an enzyme, carrying out chemical reactions necessary for life. This hypothesis is supported by the fact that RNA has both information storage capabilities (like DNA) and catalytic abilities, making it a potential precursor to the evolution of more complex proteins.

Chlorine atoms

Catalysts will lower the activation energy needed for a certain reaction to happen. For example in the extraction of Aluminium from Bauxite (Aluminium Oxide)

The melting point of Al2O3 is about 2000oC. But with the catalyst Cryolite (Na3AlF6), the overall melting point is lowered to about 950oC,

MnO can act as a catalyst in certain reactions, such as the decomposition of hydrogen peroxide. However, its catalytic activity depends on the specific reaction and conditions.
