Enzymes 2-4 Federoff

Chemical Reaction A process that transforms one set of chemicals into another.

Reactant The elements or compounds that enter into a chemical reaction.

Product The elements or compounds produced by a chemical reaction.

Activation Energy The energy needed to start a chemical reaction. Activation Energy

Catalyst A substance that speeds up the rate of a chemical reaction.

Enzymes A protein that acts as a biological catalysts.

Enzyme Analogy Frozen Thawed TOO LONG!

Enzyme Analogy Frozen + Microwave Thawed Faster!

Sometimes, catalyst can break. -What can break the microwave?

So what can cause harm… Change in pH (area becomes acidic or basic) Change in temperature (area gets too hot or cold)

Just like an enzyme…

Substrate The compound that an enzyme changes during a chemical reaction. – Or: the compound that is changed.

Enzyme Substrate Complex 1 3 2
