Understanding Enzymes and Their Functions

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.

Front

How do enzymes work?

Back

Enzymes work by lowering the activation energy required for a reaction to occur, allowing the reaction to proceed more quickly.

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is a temporary association formed when an enzyme binds to its substrate, facilitating the chemical reaction.

Front

What factors affect enzyme activity?

Back

Factors that affect enzyme activity include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is the optimal temperature for most human enzymes?

Back

The optimal temperature for most human enzymes is around 37 degrees Celsius (98.6 degrees Fahrenheit).

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can denature, losing their shape and functionality, which decreases their activity.

Front

What is the role of enzymes in digestion?

Back

Enzymes in digestion break down food into absorbable molecules, allowing nutrients to be utilized by the body.

Front

What is activation energy?

Back

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

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy needed for reactions, making it easier for the reactions to occur.

Front

What is a substrate?

Back

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