What role does the shape of an enzyme molecule play in its effectiveness? A) The shape of the activation site on an enzyme molecule is not specific so that it interacts with many different substances, allowing bonding and activation, increasing its effectiveness.

B) The effectiveness of an enzyme is dependent on the structure of the substrate activation site and not on the shape of the enzyme which is flexible and can take on many different shapes depending on the needs of the organism.

C) The shape of the activation site on an enzyme molecule does not play a significant role in enzyme effectiveness.

D) The shape of the activation site on an enzyme molecule is specific to the substrate that it must bind with. Enzymes are only effective with substances that are a fit, allowing bonding, to its activation site.
