The primary function of the digestive system is to break down food and help your body absorb the nutrients from this food. The digestive system is made up of the digestive tract‚ which includes the esophagus‚ stomach and intestines and other organs that aid in digestion such as the liver‚ pancreas and gall bladder. The breaking down of food for digestion begins in your mouth. As you eat something‚ your teeth break down the food‚ and your saliva helps to breakdown and it moistens the food so

Erin Arroyo Lab report June 11‚ 2013 Biology 123 Professor K Title: Scientific Investigation of the Peroxidase Enzyme & Temperature Abstract: In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature

The digestive system is a group of organs that perform the process by which food‚ containing nutrients‚ is eaten and broken down into different components. This breakdown makes it possible for the digested material to pass through the intestinal wall into the blood stream. The digestive process contains many different steps that take place in many different organs.<br><br>The first step of digestion begins at the mouth‚ where the food enters the mouth. Saliva is secreted from the salivary glands

Lab report April 14‚ 2013 Abstract: In this article‚ we will experiment on the significant in strength of the enzyme by using three different test tubes and measuring the amount of product they give off. To determine this we are going to test the amount of color absorbance by using a special tool to help us understand our results. We will see how our end results show the effect of the amount of concentration we apply to each test tube. The results would be shown by the support of two graphs

The Effect of Temperature on Enzyme Activity and Oxygen Production Throughout this report you will gain information as to how temperature effects the amount of oxygen produced in an enzyme- catalase experiment. In the experiment we used liver extract as a catalase and created a chemical reaction within a reaction chamber between the catalase and hydrogen peroxide as well as three different controlled temperatures. In the procedure below there will be a step by step process as to how

INTRODUCTION Enzymes are a protein serving as a catalyst‚ a chemical agent that changes the rate of the reaction without being consumed by the reaction. Enzymes are proteins made up of long chains of amino acids. These form complex shapes. The enzymes are individuals‚ like the different players on a ball team‚ they have different specific structures and jobs. As one ball player may be very tall and one short‚ the specific different shape of the active site on an enzyme is unique and prepares it

nutrients are broken down and absorbed into the body at different rates‚ and into precise arrangements‚ as they travel through the organs throughout the digestive system. • Carbohydrates are the body’s preferred energy source‚ and are found in the forms of starch‚ sugar and fibre. Additionally‚ carbohydrates move into the small intestine‚ where enzymes released by the pancreas break those carbohydrates into simple forms‚ so they can be absorbed into the bloodstream. • Lipids that are consumed‚ are mainly

BIO 5 Lab Report: Lactase Enzymes Enzymes are biological catalysts or assistants. Enzymes consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. Enzymes can either launch a reaction or speed it up. The chemicals that are transformed with the help of enzymes are called substrates. In the absence of enzymes‚ these chemicals are called reactants. Enzymes are thought to have an area with a very particular shape. When a molecule of
