No. A catalyst helps a reaction to occur but usually remains unchanged itself. Enzymes are catalysts that either remain unchanged or are returned to their original state by other biological reactions.
They're not--that sounds like a trick question :). What defines an enzyme as an organic catalyst is that they can speed up chemical reactions without being chemically altered themselves. Hence they can act over and over again, 1-10,000 reactions per second, sometimes as many as 500,000 reactions per second.
yes because enzymes are highly weighted proteins which produced from living cells and used in industrial and biological processes
enzymes are not altered. There are specific enzymes for specific chemical reactions. They are not altered during the process because they can be reused at the end of the reaction.
Yes, they remain unchanged, but sometimes they denature which means that the enzyme no longer has the same shape to perform its function.
Yes, so seductive
No they are not changed
Proteins that catalyze reactions are generally called enzymes.
Enzymes are biological substances which catalyze biochemical reactions. Enzymes can catalyze both catabolic and anabolic reactions; whether in breaking down or building up complex molecules.
Enzymes are organic molecules that catalyze reactions in living systems.
Enzymes are permanently changed by the reactions they catalyze
Enzymes allow many chemical reactions to occur. They catalyze reactions by lowering the activation energy, which is the amount of energy needed to trigger a chemical reaction. Whereas heat can provide energy to trigger reactions, temperatures needed to reach activation energy for most metabolic reactions are often too high to allow cells to survive, so enzymes are in fact needed if metabolism (anabolic or catabolic) is to occur.
they reduce the activation energy required for the reaction to occur

Enzymes lower activation energy because they have energy. Enzymes help to speed up reactions or start reactions by using their own internal energy to do so.
Enzymes are catalysts for the various chemical processes in the body. By lowering the activation energy of reactions, these enzymes catalyze the biochemical reactions necessary for life.
Enzymes catalyze certain reactions.

enzymes
Enzymes are proteins that are able to catalyze (i.e accelerate) biochemical reactions. During the course of a reaction, the enzyme is able to convert a substrate to a product but the enzyme does not get consumed in the reaction.
enzymes
Enzymes work as catalysts because they are made from long chains of amino acids. They are also soluble molecules that are proteins.
