∙ 6y agoThis crucial characteristic of enzymes is related to the Emil Fisher's formulation of his "lock-and-key hypothesis" (based on his discovery of the specificity of glycolytic enzymes to recognize stereoisomeric sugars), that is, "the specificity of an enzyme (the lock) for its substrate (the key) arises from their geometrically complementary shapes". This property is well known as Stereospecificity.

When an enzyme loses its shape it cannot fit into the active site of its substrate, which results in the enzyme being unable to catalyze the reaction and reduce the activation energy needed to activate the reaction.

Are enzymes still functional after losing their shape?
enzymes are still functional after losing their shape as they depend onn their shape
What can effect how an enzyme works by changing the enzyme's shape?
Enymes can change shape when it denatures. An enzyme can denature if it's not at the pH or temperature that it's used to. A denatured enzyme can no longer function (an enzyme's funcion: to speed up/cause chemical reactions fast enough for a living thing to survive).
How does low temperatures affect enzymes?
cold temperatures cause enzymes to inactivate, meaning they are no longer useful. at height temperatures enzymes denature, meaning they are also no longer useful. The difference is that at low temperature, when an enzyme inactivates it can always be heated, and used again. Yet after an enzyme is denatured by heat it is destroyed, this is because the heat causes the enzymes to lose its shape, making it imposible for the substrate to react with the enzyme.
What happens when enzymes unwind and change shape?
A conformational change or denaturation
What are two things that can affect the enzymes shape?
Salt concentration and the pH! also the temperature and activations and inhibitors affect an enzymes actions
How does changing in an enzyme shape cause it work poorly or not at all?
the active site would no longer fit into the substrate
Does energy cause motion and create change?
This can involve changing the shape of matter, or changing the speed or direction of an object.

How does an inhibitor affect the rate of chemical reaction?
Enzymes fasten chemical reactions, inhibitors blocks the enzymes and they will not accelerate the reaction.
Why moon is changing its shape?
The moon is not changing it's shape!
How pH levels affect enzymes?
It disrupts an enzymes shape and structure.
What are two environmental conditions that can cause enzymes to change there shape?
temperature and acidity and concentration...
Why it is important for the human body to stay close to its normal temperature?
For the enzyme to function at its best. If the temperature is to high it would cause the enzymes to denature as the hydrogen bonds in the tertiary structure is broken therefore changing the shape of the active site and no substrate can bind to it. If temperatures are to low reactions would be very slow. The optimum temperature therefore room temperature is best for the enzymes to carry its function.
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 is changing shape but not changing volume?
liquids
Do enzymes change shape after reaction occurs?
no
