What happens to an enzyme when it denatures?

• The activation energy of the reaction is doubled.

• The activation energy of the reaction is lowered.

• It's optimal conditions for temperature of the enzyme are doubled.

• The shape of the enzyme molecule is changed.

If an enzyme becomes over heated what effect, if any, will the heat have on the enzymatic activity? 

• The enzyme will not store much chemical energy.

• The enzyme will not be able to catalyze reactions.

• The enzyme will lose its net electrical charge.

• The enzyme will lose stored genetic information.
