Enzymes

Front

What are enzymes?

Back

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

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently, often around 30°C for many enzymes.

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is a temporary molecule formed when an enzyme binds to its substrate.

Front

How do enzymes speed up chemical reactions?

Back

Enzymes speed up chemical reactions by decreasing the activation energy required for the reaction to occur.

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can denature, meaning their shape is altered, which can lead to a loss of function.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme's structure is altered, usually due to extreme temperature or pH, affecting its activity.

Front

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

Back

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

Front

What is an example of an enzyme?

Back

Amylase is an example of an enzyme that helps break down starches into sugars.

Front

What is the difference between a substrate and a product?

Back

A substrate is the reactant that an enzyme acts upon, while a product is the substance formed as a result of the enzyme's action.

Front

What factors affect enzyme activity?

Back

Factors that affect enzyme activity include temperature, pH, substrate concentration, and enzyme concentration.
