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.
Amylase is an example of an enzyme. Amylase is found in our saliva and is responsible for starting to break down the starch that we eat. So amylase is an enzyme that carries out the specific reaction of breaking down starch into a simple sugar.An enzyme breaks down larger molecules into smaller molecules like sugars. -An enzyme is specific for its substrate: the enzyme that breaks down starch won't be able to break proteins down. -An enzyme is reusable, it doesn't get used up in the reaction, so it can perform it over and over again.
