Physiology & Anatomy Lab SC 145L Anatomy & Physiology I Lab Chemical and Physical Processes of Digestion Introduction: In this lab‚ we will see how different chemical processes occur as we observe how different enzymes digest different substrates and produce subunits. Key Terms: (found in bold in Lab Manual) Please define all bold terms in your own words: Enzymes- Large protein molecules made by your body cells. Catalyst- Without becoming part of the substance it will change the rate

DIGESTION OF CARBOHYDRATES Digestion of carbohydrate begins in the mouth‚ with the secretion of the enzyme salivary amylase from the serous cells of the salivary gland. This enzyme breaks starch and glycogen into disaccharides. The mucous cells of the salivary gland secrete a mucus‚ which causes the food to stick together‚ and acts as a lubricant to aid in swallowing. The salivary glands are grouped into three categories: the parotid gland‚ submandibular glands‚ and sublingual‚ all located

To achieve the goal of providing energy and nutrients to the body‚ six major functions take place in the digestive system ingestion‚ Secretion‚ mixing and movement‚ digestion‚ absorption and excretion. There are two kinds of organs that make up the digestive tract are the mouth‚ esophagus‚ stomach‚ small intestine‚ large intestine also called the colon - rectum‚ and anus all of which are hollow. Inside these hollow

Lab 8 - Chemical and Physical Processes of Digestion (p.105) Introduction: In this lab‚ I will study how digestion of carbohydrates‚ proteins‚ and fats occurs. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Enzymes (p. 105) – Speed up chemical

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

EXPERIMENT NO. 12 DIGESTION IN THE STOMACH ABSTRACT____________________________________________________________________________ Digestion refers to the mechanical and chemical breakdown of food into smaller components that can undergo absorption. The objective of this experiment is to investigate mainly the process of digestion in the stomach. The conditions at which the enzymes responsible for the digestion process were determined. Also‚ the total and free acidity of gastric juice of the sample

Human Digestion April 27th‚ 2014 SCI/241 Erica Leath The digestive system is a very interesting process that takes place after we have eaten a meal or a snack. The digestive system is responsible for breaking down the food that we have eaten and sending the nutrients to the different places in the body. The digestive is so amazing because it recognizes what your body needs and does not need and understands how to separate the two. Just like everything else in our body‚ the digestive
