Vocab 1

100

The ability to do work

Energy

200

The process of an enzyme losing its proper shape due to heat or some other factor.

Denaturation

300

The shutting down of enzyme activity due to a non-substrate binding to the allosteric site.

Allosteric inhibition

400

An indentation of an enzyme's surface where substates temporarily attach to the enzyme and react to form the product.

Active site

500

The crevice on the enzyme's surfact where a non-substrate (often a heavy metal) may bind resulting in the distortion and loss of function of the enzyme's active site.

Allosteric site

Mix

100

The law that states that matter cannot be created or destroyed but can be converted from one form to another.
