Function of an enzyme is to lower reaction's activation energy and to increase speed of a reaction, but to make it happen, enzyme and substrate must fit spatially. The shape of an enzyme is essential to make enzyme-substrate complex - if active site of an enzyme doesn't fit to substrate, there won't be a enzyme-catalised reaction.
<span>Hurricane Katrina would not have caused early onset of spring. The damaging winds/rains of the hurricane would have caused a change in marine ecosystems and habitats since the heavy winds/rain and storm surge eroded beaches, took down trees, and flooded out areas. As a result, animal migration also changed since some habitats that animals would normally migrate to were destroyed and no longer existed. The early onset of spring (aka. seasonal change) is not driven by individual weather systems.</span>
