Of course it does if there was no sun it would b impossible to grow food so yes it does
Activation energy is lowered to speed up a chemical reaction.
Enzymes are proteins that speed up chemical reactions.
Enzymes are proteins which speed up chemical reactions.

chemical reaction
An enzyme works to speed up chemical reactions in a living organism.
Yes, mechanical breakdown increases the surface area available for chemical reactions to occur on and therefore the speed of the chemical processes.
A catalyst can speed up a chemical reaction.
Anything that is added to a chemical reaction that's intended to speed up the reaction - is a catalyst.
Enzymes are proteins that speed up chemical reactions in the body.
Ensymes speed up a chemical reaction by acting as organic catalyst, a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
