It can take from 5 to10 plus years to earn a PhD in sociology, but I think 7 years about average including coursework, prelims and the dissertation.
In addition, in living systems, most biochemical reactions, including ATP hydrolysis, take place during the catalysis of enzymes. The catalytic action of enzymes allows the hydrolysis of proteins, fats, oils, and carbohydrates. As an example, one may consider proteases, enzymes that aid digestion by hydrolyzing peptide bonds in proteins.
1. The hydrolysis of pyrophosphate to orthophosphate isimportant in driving forward biosynthetic reactions such as thesynthesis of DNA. This hydrolytic reaction is catalyzed in E. Coliby a pyrophosphatase that has a mass of 120 kD and consists of sixidentical subunits.
