Which of the following statements about enzymes is not true? all options are true enzymes are regulated by feedback inhibition enzymes are regulated by molecules that bind to regions other than their active site the function of enzymes depends on their specific shape the rate of reaction for enzymes depends on the temperature

All options are true. However, the line "Enzymes are regulated by molecules that bind to regions other than their active site" is not 'always' true, since that line only describes non-competitive inhibition. There is another form of inhibition called competitive inhibition where an inhibitor binds directly to the active site of an enzyme, slowing the rate of reaction.

The correct answer is c
