Enzyme Activity and Models

Front

Why are enzymes specific to their substrates?

Back

Enzymes are specific to their substrates based on shape to perform a specific function.

Front

How does temperature affect enzyme activity?

Back

Low temperatures decrease enzyme activity; high temperatures denature the enzyme, so it cannot function.

Front

How does pH affect enzyme activity?

Back

Optimal pH results in the best enzyme activity; other pH levels decrease activity.

Front

What happens when an enzyme is denatured?

Back

The shape of the enzyme is changed.

Front

How do inhibitors affect enzyme activity?

Back

They prevent or stop enzymes from functioning.

Front

Label the lack and key model

Back

A model explaining that substrates match with specific enzymes based on shape.

Front

Why is it important for the enzyme's active site to have a specific shape?

Back

To match the substrate function in order to connect to the enzyme.

Front

Describe the lock and key model in words

Back

The parts fit like a key inside a lock; substrates match with specific enzymes based on shape
