Defn. of Digestion: the process whereby a biological entity processes a substance‚ in order to chemically convert the substance into nutrients. It usually involves mechanical manipulation and chemical action. Mechanical Digestion What is it? This type of digestion involves the mixing‚ grinding or crushing of large pieces of food into smaller places. Why does it take place? So that the food we consume is broken down into smaller pieces before we swallow it which in turn makes process of

What is pancreatic cancer? Pancreatic cancer is an aggressive form of cancer that develops in the tissues of the pancreas. Located in the abdomen behind the lower part of the stomach‚ the pancreas aids in digestion. It contains both exocrine glands (which produce enzymes that help the body digest food) and endocrine glands (which produce hormones‚ including insulin‚ that help control blood sugar levels in the body). Pancreatic cancer is hard to diagnose and once it is found it has usual spread to

! Affect of pH on Porcine Pancreatic Alpha-Amylase Activity Introduction Proteins function in a variety of different ways‚ and one of their fundamental tasks is to act as enzymes. Enzymes are extremely important in controlling reaction speed (by initiating and regulating biological activity)‚ cell communication‚ and growth. One particularly significant enzyme is amylase‚ which catalyzes the hydrolysis of alpha glycosidic linkages of amylose‚ starch components‚ and other oligosaccharides (Qian

Digestion define as a process where foods been breaking down by enzymatic action in the Gastrointestinal tract (GI tract) into nutrients in preparation for absorption. GI tract is the flexible muscular tube from mouth to anus. The digestion of carbohydrates begin in the mouth‚ where an enzyme‚ salivary amylase (α-amylase;ptyalin) starts to breaking the polysaccharides (starch) into short polysaccharides (dextrin). Dextrin is a partial degradation of starch‚ shorter chains of maltose units. Salivary

The Process of Digestion Over the course of time there have been many difficult questions and theories about everyday life. Using physiology & chemistry‚ those questions have been able to be answered. From the mixture of gases in the air we breathe to the organic substance of plastic or paper‚ chemistry can be seen everywhere. However‚ most people mistook the power of chemistry in our own bodies. How is it that a simple slice of bread‚ once consumed‚ can turn into fuel for the human body

What Are the Stages of Pancreatic Cancer? The stages of pancreatic cancer are used to describe how advanced the cancer is in your body. The higher the stage number‚ the more widespread the cancer is. These stages are important when choosing the best treatments for you. Your doctor might not be able to tell how far your cancer has spread (especially to the lymph nodes‚ which are tiny bean-shaped organs throughout the body that help fight infections) unless and until surgery is performed. For this
