Denatured Enzymes

Denature means "modifying the structure"

If an enzymes structure is altered or modified, it no longer functions properly. We considered the enzyme "denatured".

Denatured Enzymes

• Denatured enzyme loose shape and no longer function because the substrate can not bind to the active site.

• Denaturation can be caused by incorrect pH, extreme temperatures, or inhibitors

Multiple Choice

True or False: If an enzyme is denatured, it no longer functions properly.

• True

• False

Multiple Select

Select all that apply: What causes enzymes to become denatured?

• incorrect pH

• extreme temperatures

• contributors

• inhibitors

Multiple Choice

Why does changing the shape of the enzyme alter its ability to function?

• Altering the shape does not alter the function

• The substrate can not fit into the active site
