Chemical Reactions and Enzymes

Front

What happens to an enzyme when it is denatured?

Back

The enzyme's shape changes, rendering it unable to function.

Front

What is activation energy?

Back

The energy required to start a chemical reaction.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused for another reaction with the same reactants.

Front

What is the active site of an enzyme?

Back

The specific region where reactants bond to undergo a reaction.

Front

What occurs to energy during an endothermic reaction?

Back

Energy is absorbed.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as catalysts to speed up reactions without being consumed.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration.

Front

What is a substrate in the context of enzymes?

Back

The reactant molecule that an enzyme acts upon.

Front

How does temperature affect enzyme activity?

Back

Increased temperature generally increases activity up to a point, after which denaturation may occur.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to a different part of the enzyme.
