No, freezing does not denature enzymes, however; it does slow the rate at which they are able to catalyse reactions. Denaturation is a permanent change in the conformation of an enzyme that renders it useless while freezing an enzyme only results in a temporary change.

∙ 15y agoI don't think so as industrially in order to last, enzyme solutions are kept frozen and then defrosted immediately prior to use (not any later in order to optimise their activity).

∙ 14y agono. It may do strange things to them, curl them up into different shapes and all. But they will redefine themselves on re-heating or thawing and perform perfectly well again.

Is a denatured enzyme still functional?
No,they are not
What can cause an enzyme to be denatured?
Heat
What happens to the affinity between the substate and enzyme when the enzyme becomes denatured?
Affinity decreases as the enzyme's geometry is modified by being denatured. It will no longer properly fit the active site.
What does it mean when the enzyme becomes denatured?
An enzyme is a folded protein. When this folded protein becomes denatured, it essentially stops working. It can not function due to high temperatures or wrong pH.
Enzyme may lose ability to function because of what?
Shape. When an enzyme is overheated the bonds between molecules that make up the enzyme breaks, this changes the shape of the enzyme's active site. And as the enzyme is highly specific and would only work on one substrate which fits its active site, the enzyme will be totally denatured and won't activate anymore if it loses its shape.
What does denatured?
An example of something being denatured is is when an enzyme is working at a particular temperature. If the temperature goes too high, then it will destroy the enzyme and this is called denatured. I hope this helps!

What is an enzyme called when it changes shape?
An enzyme is called a denatured enzyme once it changes its shape.
What happens to an enzyme when it is heated?
When an enzyme is heated it is denatured, which means that it can no longer function.
What happens when an enzyme is denatured?
When an enzyme is denatured the active site which allows it to catalyze reactions is destroyed, rendering the enzyme useless. This process is irreversible but the remains are recycled to form new enzymes.
What can cause an enzyme to lose its confirmation?
When a protein is denatured, this can cause an enzyme to lose its confirmation.
What happened if an enzyme is at a pH significantly above or below its optimum?
Enzyme become denatured.
What does denatured mean?

What does activity of an enzyme depend on?
The concentration of hydrogen ions in solution affects the enzyme activity. Each enzyme has maximal efficiency under an optimum pH. Since pH is one of the factors for the denaturation of proteins, if an enzyme is submitted to a pH level under which it is denatured there will be no enzymatic activity.
What happens to an enzyme if it is placed in a pH outside preferred range?
The enzyme gets denatured or inactive.
