Now that you have learned about indicator solutions, write a hypothesis to answer the lesson question, “What macromolecules are present in the mystery food sample?” (Keep in mind that your teacher strongly suspects Zack, who ate tofu, is guilty.)

Hypothesis:

If the mystery food is tofu, then . . .
because . . .

100 dollars because yeah

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
