Enzyme Exit Ticket

Front

What is the 'lock and key' model of enzyme action?

Back

The enzyme and substrate fit together with rigid, complementary shapes—like a key fitting into a lock.

Front

Why are enzymes important for cellular respiration?

Back

They lower the activation energy and catalyze each step of energy extraction from glucose.

Front

What are enzymes?

Back

Enzymes are proteins that act as biological catalysts to speed up chemical reactions.

Front

How do enzymes help cellular processes?

Back

They lower the activation energy required for chemical reactions and remain unchanged afterward.

Front

What is activation energy?

Back

Activation energy is the minimum energy required to initiate a chemical reaction.

Front

What role do enzymes play in metabolic pathways?

Back

Enzymes catalyze each step of metabolic pathways, facilitating the conversion of substrates into products.

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What happens to an enzyme after it catalyzes a reaction?

Back

The enzyme remains unchanged and can be reused for subsequent reactions.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration can all affect enzyme activity.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate.
