chemical reactions involve collisions between molecules. most collisions don't have either the right orientation or enough energy for the reaction to proceed. the molecules just bounce off each other, unchanged. incidentally that is why reactions proceed faster as the temperature increases - high temperature means molecules are moving faster and are more likely to have the required energy to react.
enzymes are protein catalysts that force reactant molecules into the correct orientation and lower the required energy for a collision to produce a reaction.
Enzymes are proteins that speed up chemical reactions by lowering the activation energy needed for the reaction to occur.
Enzymes are Proteins that speed up chemical reactions.

feedback switches
An enzyme is the biological catalyst that speeds up chemical reactions.
This varies per enzyme and what it catalyzes but chemical reactions that result in an increase in temperature often speed up enzyme catalysis.

An enzyme/catalyst
An enzyme works to speed up chemical reactions in a living organism.
Enzymes speed up chemical reactions inside living organisms. They are made up of proteins.
Enzymes are used to speed up chemical reactions. One example of an enzyme is lactase which speeds the the digestion of lactose.
The kinds of chemicals that you can add to speed up the action of an enzyme are known as catalysts. Such catalysts, will be able to interact chemically with the enzymes in the reactions.
