Final answer:
Altering the three-dimensional structure of an enzyme can affect substrate binding, the type of substrate, and the energy needed for a reaction.
Step-by-step explanation:
Altering the three-dimensional structure of an enzyme can have several effects. One effect is that it can prevent the substrate from binding to the enzyme's active site, which would inhibit the reaction. Another effect is that it can change the type of substrate that binds to the active site, leading to a different reaction. Finally, altering the enzyme's structure can also change the amount of energy needed for a reaction to occur.
