grade twelve biology help; enzymes & energy :)

how is each process beneficial to the producer & the consumer...

Well, the produced doesn't have to worry much about spoilage due to bacteria and the consumer, of course, is safe from pathogens that could make him/her sick if the milk is contaminated.

Enzymes are very specific. In fact, the majority of enzymes catalyze only one type of reaction and act on only one compound or on a group of closely related compounds. There must exist between an enzyme and its substrate a close fit, or complementarity. In many cases, a small structural change, even in a part of the molecule remote from that altered by the enzymatic reaction, abolishes the ability of a compound to serve as a substrate. An example of an enzyme highly specific for a single substrate is urease, which catalyzes the hydrolysis of urea to carbon dioxide and ammonia. On the other hand, some enzymes exhibit a less restricted specificity and act on a number of different compounds that possess a particular chemical group. This is termed group specificity.

A remarkable property of many enzymes is their high degree of stereospecificity, that is, their ability to discriminate between asymmetric molecules of the right-handed and left-handed configurations.

thank you!
