Enzymes also ensure that only the required reactions take place and progress to their appropriate extent.
This field of study is called ECOLOGY. Ecology is not only the name of field of study, this term also describes interaction between organisms and their environment. (You may also use term BIONOMICS to describe this relationship.)
