Enzymes are biologic catalyst that speed up chemical reactions by lowering its activation energy Ea
No, water is not a catalyst in chemical reactions. It can act as a solvent or a medium for reactions to occur, but it does not speed up the reaction itself.
A catalyst
An enzyme/catalyst
An enzyme is the biological catalyst that speeds up chemical reactions.
Yes, it's true.
It is true that a catalyst is used in chemical reactions to help speed up the reaction by reducing activation energy.
A catalyst functions to speed up a chemical reaction without being used up in the reaction, meaning that a catalyst can be used more than once.
Anything that is added to a chemical reaction that's intended to speed up the reaction - is a catalyst.
An Enzyme.Another word used to speed up chemical reactions not necessarily in the body is a Catalyst.
A catalyst can speed up a chemical reaction. Another possible answer in the Biological sense is that Enzymes speed up chemical reactions, but these enzymes are catalysts of the chemical reactions.Different catalysts catalyse different reactions. For example iron is used as a catalyst in the Haber process (manufacture of ammonia).
A catalyst for chemical reactions in biological systems is typically an enzyme. Enzymes are protein molecules that speed up chemical reactions by lowering the activation energy required for the reaction to occur. They facilitate specific reactions without being consumed in the process.
to speed up a chemical reaction .. we use a catalyst
