Front

What term describes when an enzyme loses its shape and can no longer function?

Back

Front

What is the term for the unique substrate that fits into an enzyme's active site, as described by the lock and key model?

Back

specificity

Front

True or False: An enzyme can only be used once to speed up a chemical reaction in the cell.

Back

false

Front

What is the term for the combination of an enzyme and a reactant?

Back

enzyme-substrate complex

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and enzyme concentration.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where the substrate binds.

Front

What is enzyme specificity?

Back

The ability of an enzyme to choose exact substrate from a group of similar chemical molecules.

Front

What happens to enzyme activity at extreme temperatures?

Back

Enzyme activity typically decreases and can lead to denaturation.
