an enzyme
A substance that speeds up a chemical reaction is known as a CATALYST.
A catalyst is a substance that speeds up a chemical process without actually changing the products of reaction.
1) Something that speeds up a chemical reaction but that is not changed by the reactions is called a catalyst.2)An element is a pure substance (not a compound) and while some elements (such as platinum) can speed up chemical reactions (eg platinum in a car exhaust catalytic converter), by far the most common catalysts are in fact compounds not elements. These compounds are organic in nature and called enzymes.
There are a variety of enzymes that participate in the process of cellular respiration. Each metabolic step in the pathway is typically facilitated by a specific enzyme that effectively speeds up the rate of reaction.
In Biology, a catalyst is a substance which speeds up a chemical reaction, without being changed themselves. Biological catalysts are found in living organisms.
Catalysts
Enzyme or Catalysts
it speeds up the process :)
A protein helps form cell membranes and organelles and lso speeds up chemical reactions; an example of this type of compound is an enzyme.
A catalyst is something that speeds up a chemical reaction
catalyst-by lowering activation energy
catalyst speeds up chemical change
Yes, heat speeds up most processes including chemical weathering. Humidity and moisture likewise contribute to a speeding up of the weathering process.

A Catalyst.From wikipedia: "Catalysis is the process in which the rate of a chemical reaction is increased by means of a chemical substance known as a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. The catalyst may participate in multiple chemical transformations."http://en.wikipedia.org/wiki/Catalyst
