Are Enzymes permanently altered by the reactions they catalyze?

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.


Is it likely that enzyme that will catalyze sugar could also catalyze a protein?

no, because enzymes are specific which they only catalyze one type of reactions.


Does enzymes catalyze specific chemical reactions because the shape of their active site allows only certain substrate molecules to enter?

Yes.


What are sacs that contain enzymes that catalyze a variety of specific biochemical reactions?

Peroxisomes


Do catalyst work for any reaction?

No, a given catalyst will only catalyze certain types of reactions. Depending on the catalyst, it may be extremely specific, or it may catalyze a variety of similar reactions.


What do enzyme break down?

Enzymes catalyze specific reactions. It's theoretically possible for there to be an enzyme to catalyze pretty much any chemical reaction, so asking "what do enzymes break down" is kind of like asking "what doors do keys open."


True or false enzymes are very selective in the reactions they catalyze?

True. Enzymes are substrate-specific.


What is generally true about enzymes in cells?

Enzymes act as catalysts, and they almost always affect a specific reaction. Enzymes are proteinaceous biocatalysts that catalyze chemical reactions occurring in the living cell.


What is an enyzme made of and what is it's function?

Enzymes are made from amino acids. Once the amino acids are stringed together in a very specific order, they fold into a unique shape. That shape allows the enzyme to carry out specific chemical reactions. Enzymes are proteins that catalyze (change the rate of) chemical reactions, usually speeding up the rate.


What are proteins that catalyze metabolic reactions?

They are called enzymes; each one is specific for one metabolic reaction.


Why are enzymes almost always proteins?

The amino acids proteins allow them to have diverse structures to catalyze specific biological reactions.


What is cellular enyzmes?

any of numerous complex proteins that are produced by living cells and catalyze specific biochemical reactions at body temperatures


What are the roles of enzymes?

Enzymes catalyze reactions by lowering the activation energy needed without themselves being used up in the process. Without catalysts such as enzymes, some chemical metabolic reactions would take forever to happen or not happen at all. a specific enzyme usually catalyzes only one kind of chemical reaction


Can lactase enzymes catalyze many reactions?

Not likely. The beta-galactosidase protein that is made to cleave the glycosidic bond is specific to that operation and no others.


Why do cells use different enzymes to catalyze different reactions?

Different enzymes have specific active sites which can only catalyze one substrate. Enzyme-substrate complexes are produced only when the substrate fits into the active site.


What are enzymes and what is the lock and key theory?

enzymes are what catalyze reactions. most of the time they are enzymes. the lock and key theory simply put basically states that enzymes are the "keys" that fit into a allosteric site (the lock) and catalyze a reaction. only specific keys can fit into specific locks.


Where in the cell do all the chemical reactions happen?

Most of the chemical reactions takes place in cytoplasm however some specific reactions do take place inside nucleus.


Why do cells contain thousands of enzymes?

Because there are many thousands of reactions that are involved in the various processes of life, and enzymes generally catalyze one specific reaction or at most a family of similar reactions.


What is the name of the enzyme that doesn't change during a reaction?

Enzymes are organic molecules that are highly specific catylists for biological chemical reactions. Enzymes are not permanently changed by the reactions that they catalyze, although the may transiently change shape a little during the reaction. At the end of the reaction, the enzyme is the same shape that it was at the beginning.


What chemical reactions happen while bartending?

You need to be more specific with this question, forced chemical reactions? What happens to the patron? What happens to the drink?


Is large amounts of energy are released during chemical reactions?

This depends on the the specific chemical reaction.


Is enzymes provide energy for specific chemical reactions in cells true?

No, enzymes lower the amount of energy required to complete specific reactions. They are catalysts.


Why does gas form in chemical reactions?

This dependends on the specific reactants in the reaction.


How enzymes function in chemical reactions?

Enzymes are a group of very specific catalists in biological reactions at moderate temperatures.


Major functions of cell membrane proteins?

Peripheral proteins can be found on either side of the lipid bilayer: inside the cell or outside the cell. Membrane proteins can function as enzymes to speed up chemical reactions, act as receptors for specific molecules, or transport materials across the cell membrane.
