The Digestive Systems
The Digestive Systems The digestive systems works on nutrients taken from the environment, breaking them down into simpler products, and then absorbing the products together with water and salts so they can be used in metabolism. The individuals of all species contain many different protiens or carbohydrates in the cell walls of bacteria, chitin in the external skeletons of arthropods, and so on and foreign proteins or carbohydrates are rarely incorporated unchanged. They are usually first broke
Digestion and Absorption
Digestion and Absorption
Introduction The key issue in the digestion and absorption of fats is one of solubility. Lipids are hydrophobic, and thus are poorly soluble in the aqueous environment of the digestive tract. The digestive enzyme, lipase, is water soluble and can only work at the surface of fat globules. Digestion is greatly aided by emulsification, the breaking up of fat globules into much smaller emulsion droplets. Bile salts and phospholipids are amphipathic molecules that are present in the bile. Motility in

EMULSIFICATION AND DIGESTION OF LIPIDS BY BILE AND LIPASE
NAME : CLASS : DBT 4A DATE SUBMITTED : 14 AUG 2015 EXPERIMENT 3: EMULSIFICATION AND DIGESTION OF LIPIDS BY BILE AND LIPASE (VIRTUAL) INTRODUCTION Lipase is a type of enzyme known as a hydrolase and is responsible for catalysing the hydrolysis of triglycerides (the substrate) into fatty acids and glycerol. It is referred to as a hydrolase because the reaction that it catalyses is a hydrolysis reaction in which large molecules are broken down into smaller ones with the addition of water. Lipase is

Experiment 12. The action of lipase There are three or four liquids to be added to each test-tube, in various combinations, so look at the table at the foot of this page to get an idea of the final contents of each tube. (a) Label three test-tubes 1-3. (b) Using a graduated pipette or syringe, place 5 cm3 milk in each tube. (c) Rinse the pipette or syringe and use it to place 7 cm3 dilute (M/I0) sodium carbonate solution in each tube. This solution is to make the mixture alkaline. (d) Rinse the

Investigating the Effect of Lipase Concentration on the Breakdown of Fat in Milk INTRODUCTION: Enzymes are proteins which can catalyse chemical reactions without changing themselves. The enzyme lipase breaks down the fat in dairy products such as full-cream milk for people who are lactose intolerant. Lipase acts on its specific substrate, lipids produces fatty acids. If enzyme concentration increases, random collisions between the substrates and active sites of enzyme increase due to the increas

Investigating effect of temperature on the activity of lipase
Investigating effect of temperature on the activity of lipase This practical gives you a chance to: investigate how lipase activity changes with temperature consider how indicators can help us to follow chemical reactions. Procedure SAFETY: Keep the phenolphthalein solution away from naked flames. Wear eye protection and quickly rinse any splashes of enzyme solution or sodium carbonate from the skin. Make sure you know what to do if a thermometer is broken. Investigation a Label a test tube

Mashrek International School Effect of Different Concentrations of Enzyme on Enzyme Activity What is the effect of changing the concentration of lipase enzyme on the enzyme activity in catalyzing lipids in whole milk? Naim Al-Haj Ali MYP Year 4B  Aim: To investigate the effect of changing the concentration of lipase enzyme (2%, 4%, 6%, 8%, 10%) on the rate of enzyme activity in catalyzing lipids in whole milk (5cm3), by measuring the pH of the solution before and after adding the enzyme, keepin

Background information: Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur. The enzyme grabs on to the substrate at a special area called the active site. The combination is called the enzyme/substrate complex. Enzymes are very specific and don\'t just grab on to any molecule. The active site is a specially shaped area of the enzyme that fits around the substrate. The activity of enzymes is affected by three factors; temperature, concentration, and

Conclusions - concentration affecting lipase
Conclusions - concentration affecting lipase It is clear from the graphs, tables and statistical processes carried out that generally, increasing the volume of lipase increases the change in pH of the solution and also the rate of change of the pH of the solution. This has been proved by the increasing values of standard deviation for higher volumes of lipase, the generally larger maximum change in pH for the higher volumes of lipase and also by the shape and gradients of the graphs drawn.
