An enzyme is a biological catalyst that speeds up chemical reactions in living organisms.

Front

Which of the following is an example of an enzyme?

Back

Amylase is an example of an enzyme.

Front

What is another name for enzymes?

Back

Biological catalysts.

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 is a substrate?

Back

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

Front

What are products in an enzymatic reaction?

Back

Products are the molecules that are produced as a result of the enzymatic reaction.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, meaning their shapes are altered, which affects their function.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external stress, such as heat.

Front

What factors affect enzyme activity?

Back

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

Front

How does pH affect enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can lead to decreased activity or denaturation.
