the function of each protein is a consequence of its specific shape, which is lost when a protein becomes denatured.
The shape of a protein determines its specific function within a cell. Denaturing a protein will alter its shape, thus it will no longer function.

What happens to an enzyme and structure as it exceeds the typical human body temperature?
The enzyme can denature and will not function because it is no longer in the proper shape.
What would happen to a protein if it was exposed to extreme heat?
It would denature. Here's the way I picture it....look at an egg as a protein. In a bowl (uncooked), it has a certain shape and consistency. If you expose that egg to heat, it will change shape and consistency, right? The other thing is that once you cook the egg, you can never get it go back to the shape/condition it was before you cooked it -- you can no longer use it as an ingredient in a cake. It's the same principal with a protein...once you denature it with heat, it is forever changed and therefore, will never function the same way again -- it can never be used as an ingredient to reactions within the body.
What does it mean when a protein ''deatured'' and how does this affect the protein's function?
Proteins tend to have 3 or 4 structural levels, every protein has specific level, in which it can function. Denaturation brings protein back to the 1st structural level, so it can no longer function. For example, enzymes have the 4th structural level, then they can function. And when they are denaturated, they are brought back to the 1st level and cannot function.
Why does a protein not function after it has denatured?
Denaturation of a protein means loss of the protein's function due to structural change in the protein caused by some chemical or physical factor such as high temperature or unfavorable ph. The bonds that hold the structure together get affected which leads to the loss of structure and function
When extreme temperature changes a protein's shape so much that it can no longer perform its usual function?
denaturation
What is the effect of temperature on protein shape and give an example?
In most cases, extremes of temperature denature (alter the 3D structure of) proteins. In biological systems that denaturing temperature may be fairly mild. Another term for protein denaturing is coagulation which is what happens to the proteins of a boiled egg.

Does boiling denature cells?
Boiling can allow for the extraction of DNA.

denaturation
Do enzymes contiune to function after being frozen or boiled?
I am not sure if they work after being frozen sorry. But, once enzymes reach a certain high temperature they will denature causing them to become inactive. This process is irreversible. So therefore after boiling an enzyme it will no longer function.
How does heat denature enzymes?
Many things can denature proteins. Proteins have different optimal ranges in pH and temperature and outside of these optima then the enzyme will not work as well or at all. Also specific detergents will denature an enzyme depending on the enzyme.
What do you call the process by which acid uncoils a protein molecule?
This process is called denaturation. It can be caused by acids, bases, organic solvents, or heat. When denaturation occurs, it changes the shape of the protein. Since form follows function, a protein's function is disabled if it no longer has the form required to carry out its tasks.
How are proteins denatured in an organic solvent?
Enzymes and proteins. Denaturation unravels them, ruining their structure and therefore their function.
What happens to protein structure at low and high pH?
A change in PH can alter the 3D confirmation of the protein cauzing it to lose function partially or completely. **** A change in pH can denature a protein and also can cause it to change shape, therefore making it useless****
