it provides energy for some reactions to take place.
photosynthesis ------------------------------------------- generically a "photochemical" reaction.
Roles of film contained chemicals that were photosensitive. These could form a picture when developed.
To function as enzymes (in chemical reactions).
Clorophyll collects the light energy that is used to fuel and start the chemical reactions for photosynthesis.
we call it calvin cycle. It is making glucose.

Roles of film contained chemicals that were photosensitive. These could form a picture when developed.
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
it makes you breathe
energy is released or absorbed.
Enzymes speed up chemical reactions.
To function as enzymes (in chemical reactions).
Enzyematic reactions that occur from chemical reactions in the body speed up the activity and physiologically have everything to do with chemical reactions in the body.
All chemical reactions need a certain amount of activation energy to get started.
