Why are denatured enzymes not able to break down their substrates?

Denatured refers to the loss of the 'native' active SHAPE of the enzyme - the Active Site included; this also causes the enzymes to lose their functions.

Is potato peroxidase destroyed by boiling?
Yes, once the potato reaches a high enough temperature (approximately 55°C), the peroxidase enzyme will be denatured and no longer be able to break down substrates.
How are enzymes able to get two substrates bonded together?
They substrate bonds to the enzyme at the point known as the active site
When a protein such as an enzyme is subjected to too much heat?
The enzyme denatures, the internal bonds break. This means that the active site changes shape. This is because the arrangement of the secondary structures change After overheating an enzyme it is unusable
Are enzymes consumed in a chemical reaction?
No, enzymes are not destroyed, consumed, etc. they are reused constantly, however they can have their structure changed, which changes its function, but that does not happen during a chemical reaction.
Do enzymes change shape to move substances across the plasma membrane?
Enzymes and the substrates they work on fit like a lock and key, if you change the shape of the key, the lock won't open. An enzyme whose shape changes is no longer able to activate the reaction of the substrate.

What happens to enzymes in your body whenever your run fever?
Enzymes can not function well at higher tempatures so they become denatured and their body functions are not able to stay normal.
What class of organic molecules is damaged by high temperature?
Enzymes are proteins. They are very important because they catalyse metabolic processes in the body that would not be able to occur without them. Their function is dependant upon their shape. If an enzyme is not the correct shape for the molecules it need to bind to then it will not be able to catalyse the process it is involved in. The shapes (quaternery structure) of enzymes are the result of attractive forces between funtional groups within the protein. These attrative forces are quite weak, and high temperatures within the body will break them and the enzymes will lose their shape (they are de-natured). Once the structure is lost it cannot be reformed again, so the process regulated by any enzyme that has denatured no longer function properly.
When does it mean when an enzyme is denatured?
when an enzyme is denatured, it means that it is unable to be functional or active. for example, the enzymes in a flower for it to use photosynthesis work best at around 35 degrees celsius. once the temperature reaches past 60, the enzymes stopp working and the plant no longer is able to produce photosynthesis. denature all in all, denatured is when the enzyme is unable to work

The enzyme denatures, the internal bonds break. This means that the active site changes shape. This is because the arrangement of the secondary structures change After overheating an enzyme it is unusable
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.
Are enzymes consumed in a chemical reaction?
No, enzymes are not destroyed, consumed, etc. they are reused constantly, however they can have their structure changed, which changes its function, but that does not happen during a chemical reaction.

How does a high fever affect an enzyme?
The enzymes' activity will be changed or affected because they can not function well at higher tempratures, as the reson why people die of high fevers because the enzymes will be denatured and their body functions are not able to stay normal.
What is the relationship between digestion and enzymes?
Enzymes aid in the break down the large molecules of food products into small ones that are able to be digested (absorbed) by the intestines.
What types of conditions affect enzymes?
if the envirionment is cold, the reaction rate decreases. if the envirionment is warm, the reaction rate increases. however, if the envirinment is too hot, the enzyme will be denatured. a pH out of the enzyme's optimal range will also denature it. when an enzyme is denatured, it looses its shape a its active site is no longer able to recive the molecule and break it down.
