The substances which cause chemical reactions in a cell are protein catalysts called enzymes. Some cause reactions that would otherwise not occur and others speed reactions up. Carbon dioxide dissolves in water by itself but since this a dangerous substance to have in cells, there is a catalyst that dissolves it 300 times faster.
Enzymes are the catalysts for chemical reactions. They are capable of speeding them up and slowing them down when necessary.
A catalyst increases the rate of a chemical reaction. In cells these are called enzymes. They do not enter into the reaction nor are changed by it.
Chemical reactions in living things are usually speeded up by catalysts called enzymes.
catalyst or enzyme.
These substances are called catalysts.
A single chemical that breaks down into other substances during chemical reactions is "decomposing".
After chemical reactions new substances are obtained.
chemical reactions
Substances are changed only after the beginning of a chemical reaction.
enzymes
These substances are called catalysts.
IT ACCELATATES THE CHEMICAL REACTIONS
Reactants are substances that are changed when they become involved in chemical reactions. Products are the new substances that are formed.
A single chemical that breaks down into other substances during chemical reactions is "decomposing".
The initial substances in a chemical reaction are called reactants.
Chemical Change
Substances that are changed when they become involved in chemical reactions are called reactants. These reactants are changed into new substances that are called products.
After chemical reactions new substances are obtained.
The processes are called chemical reactions.
