EXPERIMENT 13 DIGESTION IN THE SMALL INTESTINES ------------------------------------------------- ABSTRACT The small intestine serves as the site of major digestive and absorptive processes. In this experiment‚ the action of pancreatic enzymes on representative samples of each food group under different conditions‚ such as increased/decreased pH and presence of other substances‚ were observed. A pancreatin solution was first prepared from a hog pancreas and was completely neutralized using

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

Big Idea 2 Biological systems utilize free energy and molecular building blocks to grow‚ to reproduce and to maintain dynamic homeostasis. Living systems require both free energy and matter to maintain order‚ grow and reproduce. Organisms employ various strategies to capture‚ use and store free energy and other vital resources. Energy deficiencies are not only detrimental to individual organisms; they also can cause disruptions at the population and ecosystem levels. Biological systems must both

Diabetes mellitus‚ or simply diabetes‚ is a group of metabolic diseases in which a person has high blood sugar‚ either because the pancreas does not produce enough insulin‚ or because cells do not respond to the insulin that is produced.[2] This high blood sugar produces the classical symptoms of polyuria (frequent urination)‚ polydipsia (increased thirst) and polyphagia (increased hunger). There are three main types of diabetes mellitus (DM). Type 1 DM results from the body’s failure to produce

Kelsey Choquette Derek Thiess Research Essay 30 November 2010 High Fructose Corn Syrup and Obesity High fructose corn syrup (HFCS) is one of the major caloric sweeteners used in the food industry today. It is a sweetener that contain fructose and all provide 4 kcal per gram (Suzan‚ 620). It is relatively inexpensive to produce‚ so the food industry sees HFCS an easy way to make products less expensive. HFCS is a kind of corn sugar; it is nearly identical to sucrose (table sugar)‚ which
