Step 4: Explain why the body responds to stimuli. Create a slide titled Reason(s) the Body Responds to Stimuli.
On the slide, give an explanation as to why the body responds to stimuli.
Include real-world examples of how the body responds to stimuli.
Place text in the notes section below the slide explaining the information presented on the slide. This text will act as the script for your presentation.
Remember to save your work as you go.

the awnser is d i think

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.
