When too much of a certain compound is made, the compound attaches to a separate site called allosteric site. When attached to the allosteric site, it changes the active site's shape and prevents any more to be made.

another factors include:
Concentration of the substrate (less substrate, less activity)
Concentration of the enzyme (less enzyme, less activity)
Presence of Inhibitors
Presence/Concentration of Coenzymes
Rate of Enzyme production (less production, less activity)

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.
What is the effect of excess heat or pH on an enzyme?
it can change the shape of enzymes & active site so the enzyme is unable to work
What happens when enzymes unwind and change shape?
A conformational change or denaturation
What characteristics of enzymes makes them specific for substrate?
shape of their active site make them specific for the substrates
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.
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 refers to the situation in which the binding of a substrate to the enzyme causes a change in the enzymes shape facilitating an enzymes function?
requarment of clutch
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.
What happens when globular proteins are denatured?
enzymes change shape/ unfolding of proteins
What is the effect of excess heat or pH on an enzyme?
it can change the shape of enzymes & active site so the enzyme is unable to work
What substance takes place in an enzymatic reaction but does not change shape?
Enzymes. Substrates react with the active site of the enzyme and are broken down. Enzymes stay the same throughout the reaction.
Does the active site of an enzyme have a shape that is specfic for its given substrate?
Yes all enzymes have an active site where substance are temporarily bound. All enzymes have shape that may change during catalysis. The active site of an enzyme orients its substrate molecules, thereby promoting interaction of their reactive parts.
Do enzymes change shape after reaction occurs?
no
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.
What happens when enzymes unwind and change shape?
A conformational change or denaturation
What characteristics of enzymes makes them specific for substrate?
shape of their active site make them specific for the substrates
