A catalyst like platinum is a non-biological substance that speeds up chemical reactions by providing an alternative pathway with lower activation energy. Enzymes, on the other hand, are biological catalysts that are specific to certain reactions and are essential for biological processes. Enzymes are made up of proteins and can be regulated by the cells that produce them, while catalysts like platinum are typically inorganic and do not have this level of specificity or regulation.

Why is an enzyme considered a catalyst?
An enzyme is considered a catalyst because it speeds up chemical reactions without being consumed in the process. By lowering the activation energy required for a reaction to occur, enzymes facilitate the conversion of substrates into products more efficiently.
What does a catalyst look like?
A catalyst can come in various forms such as a solid, liquid, or gas. It can appear as a powder, granules, a metallic surface, or even a clear solution depending on the reaction it is catalyzing. The physical appearance of a catalyst can vary greatly depending on its composition and intended use.
What catalyst is common in automobile exhaust?
The common catalyst in automobile exhaust is a catalytic converter, which contains precious metals like platinum, palladium, and rhodium. This device helps to convert harmful pollutants such as carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful substances like carbon dioxide, nitrogen, and water vapor through a chemical reaction.
What kind of chemical is carbohydrase is and what does it do?
Carbohydrase is an enzyme that belongs to the class of hydrolases. It functions to break down carbohydrates into simpler sugars like glucose, maltose, and fructose.
What are catalytic converters made of?
Catalytic converters are typically made of a ceramic or metallic catalyst support coated with a combination of metals such as platinum, palladium, and rhodium. These metals help to accelerate the chemical reactions that convert harmful emissions into less harmful substances like carbon dioxide, water vapor, and nitrogen.
What is an enzyme complex substrate?
An enzyme-substrate complex uses the reactants(substrates) and the enzyme. The enzyme is like a catalyst that reduces the required activation energy and speeds up the chemical reaction.

What catalyst is needed for reacting linalool with hydrogen?
A catalyst such as a metal catalyst like palladium or platinum is typically used in the hydrogenation reaction of linalool. These catalysts help facilitate the reaction by lowering the activation energy required for the conversion of linalool to its hydrogenated product while remaining unchanged themselves.
What kind of chemical is carbohydrase is and what does it do?
Carbohydrase is an enzyme that belongs to the class of hydrolases. It functions to break down carbohydrates into simpler sugars like glucose, maltose, and fructose.
Why are catalysts usually expensive?
Catalysts are usually expensive due to their specialized chemical composition, which often includes rare or precious metals like platinum, palladium, or rhodium. These metals are costly to mine and refine, contributing to the overall price of the catalyst. Additionally, the manufacturing process for catalysts is complex and requires sophisticated technology, further driving up the cost.
What is the plural form of the word 'platinum'?
Platinum, like silver, is a type of metal. You can have different amounts of a metal, but you cannot have 'three platinums.' You can have two pounds of platinum.

What is a biological compound that accelerates the rate of a chemical reaction?
It's called an enzyme it's much like a catalyst except it's organically made inside your body it's used in things like saliva and stomach acid
Is saliva a catalyst?
Saliva is not a catalyst itself, but it does contain enzymes like amylase that can help break down carbohydrates in food. These enzymes assist in the chemical digestion process, but they are not consumed or changed in the reaction.
Is catalyst is specific for each reaction?
Catalysts speed up reactions and they do this by decreasing the activation energy. The way they decrease the activation energy is by providing an alternate pathway for the reaction. Because there are so many different reaction mechanisms/pathways in chemistry, there must be many different catalysts.
