Start here! en http://biosphere.biologydaily.com/help/node/146834 hey guys, Ok so I'm required to come up with a definition for optimum conditions; this is in the context of the function of enzymes. I was going to refer to the temperature at which there is the fastest rate of metabolic reactions due to the enzymes operating best at that particular temperature. Is that all I have to consider with regard to this definition!! Would seriously appreciate some help, thx all!
