Enzyme Review

Front

What is the primary function of enzymes in biological reactions?

Back

Enzymes increase the rate of a chemical reaction by reducing the activation energy.

Front

What is an example of a common enzyme found in the human body?

Back

Amylase is a common enzyme that helps in the digestion of carbohydrates.

Front

What is allosteric inhibition in the context of enzyme activity?

Back

Allosteric inhibition occurs when a molecule binds to an enzyme and decreases the ability of the active site to bind to the substrate.

Front

What happens to the reaction rate when more substrate is added to a saturated enzyme solution?

Back

The reaction rate remains unchanged when more substrate is added to a saturated enzyme solution.

Front

What effect does adding more enzyme have on the reaction rate at a constant substrate concentration?

Back

Adding more enzyme increases the reaction rate, provided there is enough substrate available.

Front

Define activation energy in the context of enzyme-catalyzed reactions.

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is the role of the active site in an enzyme?

Back

The active site is the region on the enzyme where substrate molecules bind and undergo a chemical reaction.

Front

How do temperature and pH affect enzyme activity?

Back

Enzymes have optimal temperature and pH ranges; deviations can lead to decreased activity or denaturation.

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 cofactor, and how does it relate to enzyme function?

Back

A cofactor is a non-protein molecule that assists enzymes in catalyzing reactions, often by stabilizing the enzyme-substrate complex.
