Each enzymes had a specific job. Meaning one kind could not do what others can. Meaning having many enzymes would be advantageous (or neccessry) for our body to do many kinds of chemical reactions.
Enzymes are present throughout the body.
Everywhere.
The main function of the enzymes in the human body is to activate metabolic processes. These processes are what sustains the human life.
There is a huge amount of enzyme types in the human body. We have digestive enzymes such as pepsinogen, cardiac enzymes such as Trop-I, liver enzymes such as GGT. If you are curious of enzymes in the human body I suggest you look at specific systems or organs. An example would be to ask the internets about "pancreatic enzymes".
Well, it depends on where in the body the enzyme is located. however, all enzymes in the human body work within a very narrow temperature scale, they don't all have the exact same optimal temp, but they are close. for instance, enzymes in the scrotum have to be able to work at a temp three degrees or so lower than the average human body temperature.
Enzymes
The stomach, pancreas, small intestines, salivary glands, and the food we eat produces enzymes that live in every corner of the human body. These proteins perform different chemical function to keep the body running.
Catalysts that are called "enzymes".
Enzymes are specific proteins that increase the rate of chemical reactions in the human body.
small little lepracorns in the body which help digestion
The pancreas produces the largest quantity of enzymes in the human body. It secretes enzymes that are important for digestion, such as amylase, lipase, and proteases, into the small intestine. These enzymes help break down carbohydrates, fats, and proteins, respectively.
"There are three classes of enzymes: metabolic enzymes, which run our bodies; digestive enzymes, which digest our food; and food enzymes from raw foods, which start food digestion. Our bodies are run using metabolic enzymes. Enzymes convert the food we eat into chemical structures that can pass through the cell membranes of the cells lining the digestive tract into the bloodstream."Enzymes: are proteins that act as catalysts in mediating and speeding up a specific chemical reaction.Check out this link on the "wisegeek" website:http://www.wisegeek.com/what-are-enzymes.htmIt suggests that there are an estimated 75,000 human enzymes.Quoted using http://www.fruitarian.com/ac/Enzymes.htm and Donovanits a stuffed up question and no one shoud be put threw this stuff in science heheh :)
