A process that changes one set of chemicals into another set of chemicals.

Chemicals that enter a chemical reaction, forming products.

Chemicals formed as a result of a chemical reaction.

A protein that acts as a biological catalyst, speeding up chemical reactions.

A substance that speeds up a chemical reaction without being consumed in the reaction.

The minimum energy required for a chemical reaction to occur.

Reactants in an enzyme-catalyzed reaction.

The specific region on an enzyme where a substrate binds.

A chemical reaction that releases energy into the surroundings, often as heat.

A chemical reaction that absorbs energy from the surroundings, often as heat.

Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy.

Enzymes provide a specific active site where substrates (reactants) bind, facilitating the reaction.

An enzyme that has lost its shape and can no longer function properly due to changes in conditions like pH or temperature.

A molecule that slows down or stops a chemical reaction by blocking the enzyme's active site.

Enzymes are often named after the reaction they catalyze, usually ending with "ase".

Substrates (reactants) are converted into products at the active site of an enzyme, and then released.

The specific region on an enzyme where substrates bind and the reaction takes place.

The specific shape of the active site determines which substrates can bind and the type of reaction that occurs.
