Digestive enzymes

The digestive enzyme amylase was analysed in two different species of gastropod (the herbivorous Turbo smaragdus and the carnivorous Cominella adspersa), in order to assess whether diet influences digestive enzyme activity. This was determined by preparing a tissue homogenate from the digestive gland of each of the species and comparing their measured absorbance to that of a standard curve that reflected the relationship between absorbance and enzyme units. Amylase activity (in units of enzyme per

Action of Digestive Enzymes Jody Zimmerman Anatomy and Physiology 2, Section B1 Introduction The digestive system is a very intricate system of enzymes and other chemicals that work together to help break up our food into substances that our bodies can absorb and use. To explain it all a little better we will start from the beginning, the mouth. As we take food (Starch, protein, lipids) into our mouths we start the process with chewing which is a mechanical breakdown then salivary amylase which

This lab was conducted to learn about digestive enzymes and how they work to help break down particles. For the experiment 1(Starch/Amylase) we used 4 tubes and numbered them 1-4. We used another 4 test tubes and numbered them 1a-4a. For the test tube 1 we added 3.0ml of distilled water, tube 2 - we added 3.0ml of amylase, added 1 drop of hydrochloric acid to tube 3, boiled tube 4 until it was cloudy and added 5.0ml of cooked 1% starch to all four test tubes. We incubated all test tubes for and hour

Digestive Enzymes As a young boy, while I was playing games on Nintendo Gameboy, I used to wonder would it be easier for human beings to get energy the same way as the Gameboy did. The Gameboy receives its own energy through batteries or charging; however, human beings receive energy in a different way. A couple years later, when I went to elementary school, I realized that we received energy through a simple and familiar process: ingestion. However, what happens after we chew and swallow food was

have decided that I will test the enzymes in the digestive system on different food groups which will be processed and unprocessed foods. The processed foods that will be tested will include Doritos Cool Ranch, Fruit Loops, Slim Jim and the unprocessed foods are apples, spinach, carrots. This project divides into different subtopics the revolve around the project as a whole. The digestive system is first a review of the system and it processes, then there are enzymes and how they work and finally the

I. Science Fair question How do digestive enzymes convert sucrose and lactose into glucose? II. Background Research Do you enjoy eating smoothies packed full of berries and other tasty fruits? This paper is going to discuss how digestive enzymes convert sucrose and lactose into glucose. The following terms will be discussed: Sugar, Carbohydrates, Sucrose, and Glucose. Any of a class of crystalline carbohydrates, such as sucrose, glucose, or lactose, that dissolves in water and has the characteristic

Background & Objectives: Digestive enzymes are present throughout the digestive system and are used to breakdown various macromolecules obtained from food. An enzymes activity is dependent upon the temperature and pH at which it is present. Enzymes work optimally at specific temperature and pH levels. The purpose of this lab is to examine various enzymes to determine which substrates they digest, and at which pH they work optimally. Methods: The enzymes amylase, pepsin, and trypsin were each mixed

Abstract Intraductal Mucinous Neoplasms and Mucinous Cyst Neoplasms are two distinct entities used in categorizing non-inflammatory cystic lesions of the pancreas. Utilization of the International Consensus Guidelines for the diagnosis and treatment of IPMN and MCN assist physicians in the management of these cystic lesions while proving the highest quality of care. Introduction Intraductal Papillary Mucinous Neoplasms (IPMN) are tumors that grow within the pancreatic duct that produce thick fluid

spontaneously. Each reaction step is catalysed, by an enzyme. Enzymes are important for catalysing all types of biological reactions: those that require energy as well as those that release energy. (Metabolic Pathways, 2016) (Metabolic Pathways, 2016) Enzymes are proteins that control the rates of chemical reactions, almost all processes in a biological cell need enzymes in order to occur at a specific rate. (Barnes, Vokins and Barnes, 1998) Enzymes are selective for their substrates and only speed

if an enzyme was completely depleted during an experiment? My understanding is that enzymes have the capacity of acceleration a biochemical reaction without being consumed or depleted (Santhosh, 2017). However, a possible way to detect if the enzyme is still reacting is by seeing if the reaction is still occurring. For instance, in experiment two, after about a minute, the reaction stopped bubbling and producing gases. 2. Describe an experiment that could test the hypothesis that an enzyme binds
