An enzyme becomes denatured when:
A) the temperature exceeds the optimum temperature for that enzyme (ie the temperature that it works best at)
B) the pH of the surrounding of the enzyme is too low or too high for the optimum pH for that enzyme.
When enzymes are heated up too much they vibrate so vigorously that the bonds holding the protein structure in its specific shape becomes broken. The enzyme shape changes and the substrate no longer fits in to the active site. An enzyme which has become denatured is permanently inactive and will take no further part in reactions.

∙ 12y agoAn enzyme is a type of protein which means that it is made up of chains called polypeptides which are long chains of amino acids. The functional groups of the amino acids carry very specific magnetic charges so that they fold in a very precise way. A small change in some environmental factor such as a change in temperature or pH can change these charges slightly so that the protein looses its precise shape. This slight change in structure is known as denaturation. In other words when one of these environmental factors acts on the protein, the protein is said to be denatured. In the case of enzymes, denaturation may cause the active site of an enzyme to change shape in a way that doesn't allow the substrates to combine properly which makes the enzyme ineffective.

What is denature in science?
Denature - if it is to do with biology than it is the fact that at high temperatures, An Enzyme`s active site will change in shape, It is now Denatured.
What is the likely reason that enzyme activity is so low at 60c?
At temperatures after the optimum for the enzyme , the enzymes become denatured. This is because the active site of the enzyme becomes distorted , meaning no substrates can bind with the site in anabolic/catabolic reactions. The polypeptides that make up these enzymes unravel , which changes the quaternary structure , causing this distortion of the active site. I hope this is what you're looking for , ORCA-93 :)
What are the effects of denatured alcohol to human?
Denatured alcohol or methylated alcohol is toxic if ingested by humans. It has a debilitating effect on the nervous system and can cause death quite rapidly.
Why do eggs change in different liquids?
because there are many tiny holes in the egg's shell, and once the liquid is absorbed into the inside of the egg, the different chemicals inside the egg and it's shell react to it.
If Denatured alcohol mixes with msm what reaction will you get?
A hostile one.....*chop*
What happened if an enzyme is at a pH significantly above or below its optimum?
Enzyme become denatured.
How does acid rain affect enzyme activity?
The enzymes become denatured
What happens if enzymes are not at optimum ph?
Enzyme become denatured.
What is the name for an enzyme that has lost its ability?
No, enzymes stop working when the body dies
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!
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 is an enzyme called when it changes shape?
An enzyme is called a denatured enzyme once it changes its shape.
Why does an enzyme become denatured when heated?
Heat breaks chemical bonds in protein molecule which distorts its structure and catalytic activity .
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.
