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.
Enzyme hydrolysis Enzyme hydrolysis Enzymatic hydrolysis process converts pre-treated substrate to monomeric sugars, which could be further converted to ethanol or other value-added chemicals. An ideal enzymatic hydrolysis process is expected to yield maximum conversion of substrate to sugars at high consistency within reasonable time with least enzymatic input.
Sugars usually end in -ose (lactose, sucrose, fructose). So sucrase is an enzyme which acts on sucrose. In this case, the action is to break it down. Lactase is an enzyme which acts on lactose - in this case, the action is to break lactose down. One metabolic enzyme is pyruvate dehydrogenase. This is an enzyme which acts on pyruvate, and the action is to remove a hydrogen molecule. Just an example of an action that is not food breakdown.
