Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes lower the activation energy required for a reaction, allowing it to occur more quickly.

Front

What suffix do most enzymes have?

Back

-ase

Front

What happens to the substrate when it binds to an enzyme?

Back

The substrate is converted into a product after the reaction.

Front

What is a product in the context of enzyme reactions?

Back

A product is the substance formed as a result of the enzyme-catalyzed reaction.

Front

What does it mean for an enzyme to be reusable?

Back

An enzyme is reusable because it remains unchanged after catalyzing a reaction and can be used again.

Front

What is the active site of an enzyme?

Back

The active site is the specific region on the enzyme where the substrate binds.

Front

How do temperature and pH affect enzyme activity?

Back

Enzymes have optimal temperature and pH ranges; deviations can reduce their activity or denature them.

Front

What is enzyme specificity?

Back

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

Front

What is a substrate in enzyme reactions?

Back

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