Follow-Ups to Answer from Expert Alexander

The catalyst in question "speeds up" the destruction of collagen, the matrix forming protein in Jell-O.  Because of this, when bromelin (the enzyme in pineapple) is present, the Jell-O cannot properly form.  It is only when the bromelin has been "destroyed" by heating the pineapple that your Jell-O can properly solidify.  

Alex said most of this already, but I hope that my answer cleared up any remaining confusion you might have.

Alexander

Expertise

I can answer questions regarding all materials taught up to AP Chemistry and a majority of organic chemistry. This includes elementary, high school, and some college level chemistry. I can answer questions regarding stoichiometry, reactions, gases, thermodynamics, atomic structure and periodicity, bonding, chemical kinetics, acids and bases, spontaneity, entropy, and free energy, electrochemistry, and organic and biological molecules. I cannot answer advanced organic chemistry questions, or questions involving a high level of physics involved. Other than that, I can answer ultimately any question you have.
