Enzymes

Front

What is the primary function of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions.

Front

How do enzymes affect the activation energy of a reaction?

Back

Enzymes lower the activation energy required for a reaction to occur.

Front

What is a substrate in the context of enzyme activity?

Back

A substrate is any substance that is acted upon by an enzyme.

Front

What happens to enzymes when they are exposed to high temperatures?

Back

High temperatures can denature enzymes, altering their shape and function.

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is the intermediate formed when an enzyme binds to its substrate.

Front

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

Back

The active site is the region on the enzyme where the substrate binds and the reaction occurs.

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and enzyme concentration.

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 the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can reduce activity or denature the enzyme.

Front

How do competitive inhibitors affect enzyme activity?

Back

Competitive inhibitors compete with the substrate for binding to the active site, reducing enzyme activity.
