What happens to enzyme ability to catalyzes a reaction when enzymes are heated?

When heated too much, enzymes (since they are proteins dependent on their shape) become denatured. When the temperature drops, the enzyme regains its shape. ... Changes in pH will also denature the enzyme by changing the shape of the enzyme. Enzymes are also adapted to operate at a specific pH or pH range.

Heating an enzyme denatures the structure and reduces or turns off function!

Explanation:

Enzymes are proteins that increase the speed of a reaction. Heat denatures the structure of an enzyme, which causes it to lose function!

There are the Three 'F's in Biology... Form Follows Function, if you alter the form you also alter the function of something in Biology!

not: both offer magnification to the atomic level.
