When this happens to a protein, it is said to denature.Denature is caused commonly by very high or low temperature,concentrated acids or bases.Denature by high temperature is irrevesible.

A permanent change in the shape of the enzymes active site caused by high temperatures?
A permanent change in the shape of an enzyme's active site caused by high temperatures is called denaturation.
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 an enzyme a structural protein or functional protein?
Yes, enzymes are proteins and it is their sequence of amino acids (primary structure) that determines what kind of an enzyme it is and makes all the enzymes unique and it is the tertiary structure of enzymes that maintains their shape and give rise to the unique active site. When an enzyme is denatured, it loses its tertiary structure and therefore its shape.
What characteristics of enzymes makes them specific for substrate?
shape of their active site make them specific for the substrates
What is denaturing And what causes enzyme denaturing?
Enzymes are proteins that help speed up the the rate of chemical reactions in the human body. Enzymes possess a specific shape and this shape fits into the substrate. When an enzyme becomes denatured, it loses its shape and thus it cannot function effectively. Enzymes may become denatured due to high temperatures or changes in the pH.

Why must a molecule have a specific shape if it is to be a substrate of an enzyme?
Active sites of enzymes (where the substrates fit in) are substrate specific, and are complementary to the shape of the molecule (substrate). In this way, enzymes can only act on a specific substrate, since that is the only shape that it will accommodate in the active site.
By what mechanism do enzymes work?
Enzymes work in a variety of different ways. When a molecule of a correct chemical comes along it will fit exactly into the shape. This is called the active site of the enzyme because this is where the reaction takes place.

What is the induced fit theory?
The induced fit theory proposes that the active site of an enzyme changes its shape upon binding with the substrate. This change is induced by the interaction with the substrate, leading to a more precise fit and optimal conditions for catalysis to occur. This theory suggests that the binding of a substrate to an enzyme is a dynamic process rather than a static lock-and-key model.
What characteristics of enzymes makes them specific for substrate?
shape of their active site make them specific for the substrates
How are enzymes damaged by high temperature?
The body has its own normal temp. And enzymes function along with body temp, you go to high or low it can cause severe damage to the body. Enzymes are proteins, and they are denatured (change in structure) when expose to high temps.
What happens when globular proteins are denatured?
enzymes change shape/ unfolding of proteins

When an enzyme becomes denatured, it loses its shape and thus it cannot function effectively. Enzymes may become denatured due to high temperatures or changes in the pH.
What determines the shape of an enzymes active site?
The active site is part of an enzyme where substrates bind and undergo a chemical reaction.
What happens when an enzyme loses it's shape?
Its molecular shape is altered so the substrate cannot fit to its active site
