After being heated, an enzyme loses its ability to catalyze a reaction. What change occurred to the enzyme?

A. A chemical change, because it can no longer react in the same way
B. A physical change, because intermolecular forces were overcome
C. A physical change, because cooling will restore the enzyme's function
D. A chemical change, because the chemical bonds between its atoms were broken

@aaronq It's either B or C right?

aaronq · Answer

it's B, if you heat an enzyme you break intermolecular forces holding the protein in it's functional configuration
