Download file to see previous pages These compounds are further subdivided into many classes such as Carbohydrates into monosaccharides and polysaccharides, Proteins into amino acids and lipids into triglycerides and fatty acids (Saturated and Unsaturated). All these compounds which form the basic requirements of our body and food contribute in the process of formation of ATP, the basic energy providing compound of our body. These biochemical compounds when enter our digestive system are further broken down into their very basic compound or particle which then undergoes the process of metabolism (either anabolism or catabolism) to form ATP. Our digestive system consists of oral cavity where food is chewed, esophagus for the transfer of chewed food, stomach for the breaking down and absorption of some of the food specially Vitamin B12 and proteins and intestines (small and large) for the further absorption and digestion of remaining undigested food and removal of left over undigested food through the anal canal. All these systems form the basis of body’s energy providing system along with liver where most of the absorbed compounds are taken and there they undergo the process of metabolism to form the basic energy providing compound of the body. An abnormality in any of them e.g. hepatitis, peptic ulcers could lead to less nutrition supplied to the body ( malnutrition) and even ...Download file to see next pagesRead More

... Ordinary Men “Ordinary Men” by Christopher Browning is a profoundly depressing book. Please, let the reader understand, it is not the endless litany of how many Jews were killed on this day or how many were transported on that day. No; Browning has wrought a work which showcases the “ordinary men” following orders, doing their job because those are the orders they were given. The first incident at Jozefow seared the consciences of the men involved and after that, what was left? Who could protest anything after participating in a bloody massacre, herding men, women and children into a woods and shooting them in cold blood? As Browning demonstrated, well over eighty percent of the battalion’s men neither protested nor objected... Ordinary Men...

Energy, Metabolism and Cells

...molecules are produced from the NADH and FADH molecules through the enzyme ATP synthase (Simmons, n.d.; Gregory, 2011). The net number of ATP produced by cellular respiration is therefore 32, with 2 from Glycolysis, 2 from the Krebs Cycle, and 28 from the Electron Transport Chain. This ATP is utilized by the plant and animal body for their daily activities. Fermentation Some living things like anaerobic bacteria do not have oxygen in their systems and therefore resort to anaerobic respiration in order to produce the ATP they need for their various metabolic processes. The same goes with eukaryotes with a low oxygen supply. In such organisms, therefore, pyruvic acid from glycolysis goes through...

The Anatomy of Human Digestive System

...?The Anatomy of Human Digestive System Introduction Digestion is the process wherein food is mechanically and chemically breaks down into smaller pieces small enough to be utilized and absorb by the body. The human digestive system beginsfrom the mouth, passed through the esophagus, stomach, and the intestinesup to the anus for elimination. Digestion starts with the processing of food mechanically in the mouth. Food is crashed and grounded by teeth, the process is called mastication. This increases the surface area that makes it easier for enzymes to break it down further. Enzymes from the saliva also help to soften the food and breaks...

... the many benefits vitamin C may provide, that mandate is deceptively simple.  Function in the body:  Much like the immune system itself, which operates at a cellular level, the hardworking vitamin C penetrates every cell of the body. The concentration of vitamin C in both blood serum and tissues is quite high.  Vitamin C helps some of our most important body systems. The most vital function is that it helps the immune system to fight off foreign invaders and tumor cells. Vitamin C also supports the cardiovascular system by facilitating fat metabolism and protecting tissues from free radical damage, and also assists the nervous system by converting certain amino acids into neurotransmitters.  The skin, teeth and bones also benefit... ...

Digestive system

...Human Anatomy Lab Report Topic: Digestive Systems Saliva aids in formation of food boluses in addition to lubricating, protecting, and cleansing the pharyngeal and esophageal mucosa. Enzyme amylase catalyzes breakdown of starch into sugars (trisaccharides and disaccharides); these sugars are later converted to glucose which supply energy to the body in form of ATP. 2. Enzyme pepsin helps in degradation of food proteins into peptides. Gastric gland also secretes other substances, such as enzyme rennin that curdles milk. Hydrochloric acid (HCL) produced by parietal cells activates enzymes that are in inactive form to active form: for instance pepsinogen (inactive form) to pepsin (active...

...changes in my body after taking some foods. For example, eggs made me have an itchy throat, made me hyperactive, and made me have dazed thinking. However, I should point out that this was only in instances when I took four eggs. Nonetheless, taking one egg did not give me any of these symptoms. Consequently, I realize that I need to stop taking this number of eggs in order for me to stop these changes in my body systems. On the other hand, I have realized that taking muffins also came with deleterious effects. In this case, I experienced symptoms related to congestion of the sinus, headache, and my throat constricted. I did not know what occasioned these symptoms, but I realized that one of the ingredients in the muffins...

... Task Printing A Human Kidney Antony Atala outlines how recently there has been a needing for growth and replacement of body parts through used of modern day science in the lab. He outlines how regeneration is critical and how aviators like Charles Lindberg explored and researched on regeneration in early in 1930s with high hopes of finding a lasting solution. These ideas have been persistent due to the great admiration and desperation for patients to replace their organs. He outlines how in every second patient die when there is a capability to survive if the organ or a tissue is replaced (Whatley and Stuart 12) Recently regenerative medicine has become a fact in science and used in areas of cell therapies in advancement...

...Fictitious Experiment Fictitious Experiment Option A: Grass Growth Experiment Introduction The experiment Option A was purposely conducted to study the effects of salt of the growth of grass. To do this, salt was spread on a driveway on daily basis during winter. Later, its effects were observed during spring when the grass was to start growing. To compare the results, a control experiment was also carried out. Hypothesis Salt has an inhibition effect on the growth of grass Control Experiment Along side the experiment, a control experiment was done by using grass and allowing it to grow in normal conditions without using salt. This was necessary as it would help in comparing the effects of salt on the growth of grass. Results... Experiment...
