Catalysts and Catalysis

No, a catalyst does not change the overall energy of a reaction. It only lowers the activation energy required for the reaction to occur. Therefore, a catalyst cannot change an endothermic reaction into an exothermic one.

An apparatus, such as a large fermentation chamber, for growing organisms such as bacteria or yeast that are used in the biotechnological production of substances such as pharmaceuticals, antibodies, or vaccines, or for the bioconversion of organic waste.

In a denatured enzyme, the three-dimensional structure of the enzyme is disrupted, leading to loss of its biological activity. This can be caused by factors such as changes in temperature, pH, or presence of denaturing agents, which alter the interactions that maintain the enzyme's structure. Once denatured, the enzyme may lose its ability to bind to its substrate and catalyze a reaction effectively.

Enzymes are a type of catalyst. A catalyst is used in a biochemical process to reduce the activation energy needed for a specific reaction.

Yes - but biological catalyst would be an even better description.

No, a catalyst is not a compound itself. A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It remains unchanged chemically at the end of the reaction.

Some enzymes found in peroxisomes include catalase, which breaks down hydrogen peroxide, and various oxidases that participate in fatty acid metabolism and help generate hydrogen peroxide. These enzymes play a crucial role in breaking down toxic substances and lipid metabolism within peroxisomes.

A kinase enzyme adds phosphate groups to proteins, a process called phosphorylation. This modification can change the activity, function, or location of the target protein, which is crucial for many cellular processes such as cell signaling, growth, and differentiation.

Enzymes

No, sand is not an organic catalyst. Organic catalysts are typically made up of carbon-based compounds, while sand is primarily composed of silicon dioxide. Sand is more commonly used as a support material or for providing surface area in catalyst systems.

d-block elements can act as catalysts because their partially filled d orbitals allow them to easily donate or accept electrons during chemical reactions. This property enables them to form stable intermediate complexes with reactants, lowering the activation energy required for the reaction to occur, thus speeding up the reaction. The ability of d-block elements to change oxidation states also contributes to their catalytic activity.

No, enzymes are mainly made of proteins. Enzymes are biological catalysts that speed up chemical reactions in living organisms. While some enzymes may have components that contain fat (lipids), the overall structure and function of enzymes are based on proteins.

That depends on weather it is combining or separating the two substances. If it combining the two, then the 2 substances will both attach to the enzyme's active site (where the combination/separation occurs), where the enzyme will then just squeeze the 2 substances together. If it is separating the two, the the substances will again attach to the active site, but the enzyme will then contort itself so that the items will be separated by simple force. You may also want to note the an enzyme is NEVER used up after reactions. Individual enzymes undergo many reactions.

Enzymes are the globular proteins which are responsible for altering the rate of reactions inside all organisms - i.e. they are biological catalysts.

The correct answer is a simple one: The system is unaffected by a catalyst in a system in equilibrium.

Yes, an enzyme is a substance, an organic substance, because it is a protein, and all proteins contain carbon, which is the definition of an organic substance.

I had to find this out for Biology GCSE and found that not many people actually knew. Hope it helps

Monounsaturated fat is a type of fat that is composed of fatty acids containing one double bond in the fatty acid chain. It is a compound, as it is made up of carbon, hydrogen, and oxygen atoms bonded together in specific arrangements.

Digestive fluids contain various catalysts such as enzymes, which help break down large molecules into smaller ones for absorption and utilization by the body. Some common enzymes found in digestive fluids include amylase, protease, and lipase, which assist in the digestion of carbohydrates, proteins, and fats, respectively.

Factors such as extreme pH levels, high temperatures, or exposure to certain chemicals can denature an enzyme, altering its shape and rendering it ineffective. Additionally, changes in the enzyme's substrate-binding site can occur due to mutations or inhibitory molecules, preventing it from catalyzing reactions.

Enzymes are catalysts because they speed up chemical reactions by lowering the activation energy needed for the reaction to occur. They do this by binding to specific substrates and altering their molecular structure, making it easier for the reaction to take place. Enzymes remain unchanged after the reaction is complete and can be reused multiple times.

Enzymes function as catalysts by lowering the activation energy required for a chemical reaction to occur, increasing the rate of the reaction. They do this by binding to specific substrates and facilitating the formation of an intermediate, which then breaks down into products. Enzymes are not consumed in the reaction and can be used repeatedly.

Catalysts are substances which speed up the rate of reactions, without changing in chemical formula or mass themselves. Enzymes are basically biological catalysts, which break down substances like complex carbohydrates into simple sugars; or long chain proteins into usable amino acids. Without them, these vital reactions would take place too slowly and we would die.

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. Catalysts work by providing an alternative pathway with lower activation energy for the reaction to occur. They can be elements, compounds, or enzymes that facilitate reactions without being permanently altered themselves.

when an atom loose electron it become negative ion and when it gains electron it become positive ion
