Enzyme flashcard 24

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.

Front

What does it mean for an enzyme to be reusable?

Back

An enzyme is reusable because it can catalyze multiple reactions without being consumed or permanently altered in the process.

Front

What happens to an enzyme when it is denatured?

Back

When an enzyme is denatured, its structure is altered, which can result in a loss of its catalytic activity.

Front

What is catalase and what is its function?

Back

Catalase is an enzyme that catalyzes the breakdown of hydrogen peroxide into water and oxygen.

Front

What effect does boiling have on enzymes like catalase?

Back

Boiling can denature enzymes like catalase, rendering them inactive and unable to catalyze reactions.

Front

Which of the following is an enzyme: Sucrose, Galactose, Fructose, Amylase?

Back

Amylase is an enzyme that helps in the digestion of carbohydrates.

Front

What is a substrate in the context of enzyme activity?

Back

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

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions by lowering the activation energy required.

Front

What does it mean for an enzyme to be specific?

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a particular substrate among many.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without undergoing any permanent change itself.
