A protein is denatured because of high temperatures or changes in pH. When it is denatured, it means that the protein has lost its original shape and therefore, it cannot function properly anymore.

A protein can become denatured when?
A protein can become denatured when a number of things happen. Some of them are the loss of solubility by the protein as well as cooking proteins will cause them to be denatured among others.
What is broken if a protein may become denatured?
petide bonds
Do changes in salt concentration cause proteins to become denatured?
denaturation of protein by salt?
Why is it important not to heat the food substance which is being tested for protein?
Proteins that are heated to a very high temperature will become denatured, and inactive
If a proteins shape is changed it has been?
If a proteins shape is changed it has likely been denatured. This is often a breakdown and rearrangement of the protein.

What is broken if a protein may become denatured?
petide bonds
What does a globular protein become when its hydrogen bonds are broken?
Denatured
Breaking the weak bonds of a protein causes it to become?
Denatured and ineffective.
What happened to the structure of catechol oxidase at temperatures above 75C?
it is "denatured" - its structure become very much distorted and thus the protein cannot work anymore
What is protein denatured by?
A denatured protein has had its structure dismantled or altered, rendering it disfunctional or nonfunctional, and therefore useless.
What is the name for an enzyme that has lost its ability?
No, enzymes stop working when the body dies
What is likely to happen to a protein molecule that is exposed to intense heat or radiation?
A protein may become denatured when exposed to intense heat or radiation. When a protein becomes denatured, its basic structure is damaged enough that it is no longer able to function.
Do changes in salt concentration cause proteins to become denatured?
denaturation of protein by salt?
What happened if an enzyme is at a pH significantly above or below its optimum?
Enzyme become denatured.
Is it impossible for a denatured protein to regain its shape?
It depends on the protein and how it was denatured - but no, not impossible. Sometimes it can be reversible, but it's usually only reversed in a test tube. Things become complicated in the actual biological system.
Why does an enzyme become denatured when heated?
Heat breaks chemical bonds in protein molecule which distorts its structure and catalytic activity .
