The Digestive Track The BIG MAC is placed in the mouth. The bread is mainly starch‚ the special sauce is mainly fat‚ lettuce‚ pickles‚ and onions are niacin. The beef patties are protein‚and cheeseis a form of calcium‚ fat‚ and protein. The piece of the BIG MAC is placed in the mouth and chewed‚ the starch is being digested by saliva. The starch becomes a kind of sugar which is used as a nourishment for the cells. Saliva changes food to a form that can be used by the body called enzymes.

Biography - An Account of his life (1879-1981) Reverend Henry Ward was born in Golden Grove‚ St. Ann. He received his early education at Clapham Elementary School‚ and then moved on to St. George’s Elementary in guys Hill. There he passed the Pupil Teachers’ Examination with distinction and gained an exhibitioner’s scholarship to the Micro Teachers’ College. He distinguished himself at Mico‚ and his personal conduct was exemplary throughout his college career. In 1900‚ he graduated from Mico as

In this lab we tested the effect of temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the difference absorbance levels they produced every 20 seconds for about 2 minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was at lower temperature we got very low numbers for the absorbance‚ which gave us a lower

Effect of Temperature on Enzyme Activity Bernard Stepteau Biology Lab 101/Th 8:00am – 9:50am 2-26-2014 Dr Laynes Hypothesis: As the temperature of the enzyme catalase rises the activity of the reaction will decrease. Objectives: The objective is to compare catalase activity at different temperatures. Introduction Catalase speeds the breakdown of hydrogen peroxide. Catalase is present in every plant and animal organ. This is useful because hydrogen peroxide is harmful

Title: Enzyme Activity Lab Purpose: To measure the rate of enzyme activity from a tissue abstract and experiment with different factors‚ such as the enzyme solution and the substrate with different hydrogen peroxide percentages and temperature‚ that affect enzyme activity. Hypothesis: 1) If the disk is placed into each beaker with 100 units/ml of enzyme solution‚ then the time for the disk to float will be 30 seconds. 2) If the temperature of the solution is at 5 degrees Celsius‚

Purpose The digestive system prepares food for use by hundreds of millions of body cells. Food when eaten cannot reach cells (because it cannot pass through the intestinal walls to the bloodstream and‚ if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Physical and chemical modification (digestion) depends on exocrine and endocrine secretions and controlled movement of food through the digestive tract. Mouth Mouth

Activity 1: Simple diffusion Introduction: Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration so its overall net movement is along the concentration gradient‚ simple diffusion does not require energy therefore it is ’passive’‚ substances are diffused across the membrane between the phospholipids.
