digestion of milk fats by pancreatic lipase and the digestion of proteins by pepsin and trypsin By Jenny Lam Abstract The purpose of this project was to determine how pancreatic lipase and bile salts digest fats to fatty acids and glycerol and how pepsin and tryspin digest to polypeptides. Litmus solution (pH indicator) was used for the fats to indicate the occurrence of the digestion of fats in experiment A. Egg whites was used as the substrate for the enzymes in experiment B. The pH

Bread is made out of carbohydrates. In the digestive system‚ carbohydrates start the digestive process in the mouth. Salivary amylase is created by by three large salivary glands. This amylase breaks down starch and carbohydrates. However‚ since only a few people keep the food in their mouth long enough for the amylase to digest the

left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus‚ it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food. The lining of the stomach secretes hydrochloric acids and enzymes that break down the food so that it can continue on its journey through the digestive system. As it secretes acid and enzymes‚ the stomach muscles contract in a process called

Owl Pellets Introduction Owl pellets are masses of bone‚ teeth‚ hair‚ feathers and exoskeletons of various animals preyed upon by raptors‚ or birds of prey. Owls have weak stomach muscles that form undigested bones‚ feathers‚ and fur. Because they can’t break those things down they regurgitate them in the form of a ball called a pellet. Owls produce these pellets and regurgitated them approximately 20 hours after eating. The purpose of this lab is to dissect an owl’s pellet and investigate

method of food gathering and energy needs are some factors that influence the type of digestive system an animal needs in order to survive. Herbivores have a more specialised digestive system than that of a carnivore because it is more difficult to digest vegetation than meat. The teeth are flat so that grass and plant material can be ground down‚ rather than the sharp teeth of carnivores designed to tear flesh. Animals which eat both plants and meat‚ such as humans‚ have both types of teeth so that
