I dont know who else to ask!

Hi there ! First off, don't get discouraged. I know this class is important, but if you look at the great picture of life it means nothing. You are going to make it through and everything will be fine.

I can give you some suggestions on how to make it through this class. Go and by physician's diagnosis and treatment book or a nursing med-surg book.

Look up " enzymes" and you will get your answers.

I would probably pick digestive enzymes - without them food would not be absorbed into body.

Other types of enzymes serve as catalysts in chemical reactions, without them synthesis of chemicals will not be possible, therefore disrupting body function.

Look up with they are.

Don't get stressed too much, everything will be OK.

Thank you :) ... would I go to a regular book store to get that? Do you know exactly what its called... ?

WOW I am SO thankful for you guys...

This website is such an awesome resource.. & thank you all for your responses!!

Look up Tay-Sachs disease. There are many, many others....I don't mind giving someone a little nudge once in a while, as long as they're not fishing all the time for direct answers....

Edited to add - oops, I feel ridiculous. I was just trying to help and didn't realize someone had already recommended Tay-Sachs!

Ok, I still cant figure anythign out for the first essay.. This class is just killing me.. I have no idea what to put for any of these essays, I spend hours googling the vocab words we need to include, and I just cant find any real life medical situations where this would be included...

The first question again is " What is the role of enzymes in biological systems & what are two or three examples of important enzymes and how they are used in teh human body?"

I finished the explaination about that which was:

Enzymes are catalysts that assist in multiplying the speed in which reactions would get done in a biological system. The enzymes are protein molecules that offer a stable environment for reactions to take place, called the active site. Without enzymes, cellular reactions would take place too slow for life to keep going.

Three different types of enzymes that are important to the human body include digestive, metabolic, and food enzymes. Digestive enzymes are in the mouth when you eat in the form of saliva. They are secreted along the digestive tract and used to break down the food we eat. This enzyme allows food that we can used to be absorbed into the blood stream, and the food that we don’t need to be excreted. Metabolic enzymes are produced in the cells. They are found in large quantities in the liver and pancreas. Metabolic enzymes increase the speed of reactions in these areas that are involved in energy production and detoxification. Every cell in our body depends upon these reactions. The third type of enzyme found in the human body is food enzymes. These enzymes come from raw food. The food enzymes are killed when cooked, because the temperature rises past the point for the reactions to take place. Because we don’t eat much raw food, supplements are usually taken in replace of these food enzymes.

But I dont know what to put for the paragraph explaining how I would use what I learned in a medical standpoint...

The second essay I used your advice on teh Tay- Sachs disesase, but my essay is really short...

Enzymes are a very important part of the body, or any biological system. Without them, the liver would be unable to function, to get rid of the toxins in the system, and biological reactions would be slower, or completely unable to take place.

An example of a disease that results in defective enzyme production is Parkinson’s disease. Parkinson’s disease occurs when the nerve cells in the brain die. The enzyme that is protecting this nerve is called GST pi. The enzyme blocks the biochemical pathways so that nothing destructive, like pesticides can enter and destroy those cells. This disease causes trembling, lack of coordination, and loss of muscle control.

In the medical field, more specifically, a OB/GYN or Pediatric nurse could potentially have to deal with many diseases or disorders that can occur due to a lack of enzyme or destroyed enzyme. One disease in particular is called Tay-Sachs disease. A neurological enzyme that is important for development in vision, movement and hearing is called Hexosaminidase A. This enzyme is an antioxidant against fatty proteins and other material that builds up in the brain. When that enzyme is not present, the excess material is able to build up, therefore causing lack of abilities to see, speak and hear, and eventually death.

If you guys have any comments or corrections, or wanna help, I'll owe you!! I keep trying to talk to a tutor, which are online cause this is an online class, and they are only open when i have work! geez....

Sounds good to me.

I would have recommended something similar...pancreatitis.

You would need to understand the action of enzymes in order to understand the patho. Treatment used is dependent upon this knowledge as well. Sometimes it is necessary to avoid food during acute attacks to allow the pancreas to rest, since the pancreas releases the enzymes in response to food that is consumed. The pt may require short term TPN (total parenteral nutrition). Sometimes in cases of chronic pancreatitis, pancreatic enzymes must be added to each meal in order for the pt to digest food, decrease pain, and maintain proper nutritional status.

Enzymes are necessary in DNA replication. Do a search for polymerase, helicase and ligase.

I feel for you! I have found that the online classes that I have taken have been more difficult then my actual classes. I asked one Professor why it seemed that online classes were more writing intensive and she told me that online has to have a specific number of typed words by the student..don't know if this is actually correct, but I can tell you I typed a lot of words in her class, and since have attempted to stay away from online classes.

Good Luck to you. I can totally relate to your stress. Once I feel stressed/overwhelmed, someone could knock me over the head and it wouldn't effect me.

Relax this is nothing compared to what they will ask of you next. One thing I did for my pre-req's is I went to askjeeves and i typed in my essay questions and jeevs took my to the answer.

Good Luck
