Lab Flashcard Enzymes

Front

What is a substance that is acted upon by an enzyme called?

Back

Substrate

Front

What happens to enzymes when they are heated to a high temperature?

Back

The shapes of the enzyme are altered (denatured).

Front

What is the term for an enzyme that works best in a basic solution?

Back

Enzyme B (specific example may vary).

Front

What do we call a substance that speeds up a chemical reaction?

Back

Catalyst

Front

What is the term for the ability of an enzyme to only bind to one specific substrate?

Back

Specificity

Front

What is the role of a coenzyme in enzyme activity?

Back

Coenzymes assist enzymes in catalyzing reactions, often by acting as carriers for chemical groups.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external factors like heat or pH.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds and the reaction occurs.

Front

How do temperature and pH affect enzyme activity?

Back

Enzymes have optimal temperature and pH ranges; deviations can reduce activity or cause denaturation.

Front

What is enzyme reusability?

Back

Enzymes can be used multiple times in reactions without being consumed.
