Alvaro Comino LAB REPORT 4 CONNECTIVE TISSUE (SPECIALIZED) I. Abstract In this experiment‚ identification and classification of different types of connective tissue was performed. Also‚ cells and extracellular matrix was to be identified in them. For this‚ different already prepared slides were chosen and observed under the microscope to then identify the different parts. II. Introduction Apart from the bone and cartilage‚ the rest of the specialized connective tissues are divided

Rate of Enzyme Activity Justin Hunter G. Kim September 16‚ 2011 September 26‚ 2011 Abstract Catalase is a common enzyme found in nearly all living organisms that is frequently used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less reactive oxygen and water molecules. Catalase is a protein that is most commonly found in the liver. The purpose of this experiment was to determine the effect that changes in temperature and pH have on the function of the enzyme catalase

Lab 1 Diffusion‚ Osmosis‚ and Water Potential of Glucose Problem: What effects will glucose have on diffusion‚ osmosis‚ and water potential? Background: All living things have certain requirements they must satisfy in order to remain alive. These include exchanging gases (usually CO2 and O2)‚ taking in water‚ minerals‚ and food‚ and eliminating wastes. These tasks ultimately occur at the cellular level‚ and require that molecules move through the membrane that surrounds the cell. There

Enzymatic activity of Human saliva (Salivary amylase) against Temperature Proponent: Ian Angelo P. Dela Cruz BS-Biology 1-3 Prof. McJervis S. Villaruel Professor – BIOL2015(Lab) ABSTRACT This report entitled “Enzymatic activity of Human saliva (Salivary amylase) against temperature” aims to know and observe the enzyme activity of the human saliva. The research only included the use of starch-agar as the medium to observe enzyme activity during the experiment. Five starch-agar

Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

Amylase Enzyme vs. Starch vs. pH vs. Temperature Taylor Ellsworth Professor Michael Bunch Cell Biology 112 “Effects of Amylase reaction time when breaking down starch.” Experiment Goal: The goal of our experiment was to understand the similarities in digestion by finding out how long it takes for the amylase enzyme‚ found in saliva‚ to break down our substrate‚ starch. Hypothesis: While understanding that starch is broken down by our saliva (amylase enzyme) we predict that the higher

Enzymes are catalysts that speed up chemical reaction but are not themselves consumed or changed by the reaction. The cell’s biological catalysts are proteins. Proteins are made up of one or more polypeptide chains that are folded to make an active site‚ an area in which a material to be acted on by the enzyme‚ called the substrate‚ will fit. The temperature‚pH‚ the concentration of enzyme‚ and the concentration of substrate all affect the activity of the enzyme and the rate of the reaction. The

THE RATE OF ENZYME ACTIVITY. To investigate the effect that temperature has on enzyme activity I am going to use the enzyme amylase‚ which is used as a biological catalyst to break down starch‚ which cannot pass through the gut wall due to the size of the molecules‚ into smaller ones. Amylase is a carbohydrase‚ which converts starch to simple sugars in the Salivary Glands. Three features of all enzymes are: They are always proteins. They are specific in their actions and each enzyme controls one

Names ……………………………………………………….. How sensitive is skin to touch? The receptors for the sense of touch are scattered over the surface of your entire body‚ however those receptors are more closely grouped together in certain parts of your body. In this activity you will investigate the distribution and sensitivity of the touch receptors in the human body. Procedure 1. Obtain 8 large paperclips‚ a ruler‚ and masking tape. 2. Bend paperclip to form a “U” or “V” shape so the ends are 1/2 centimeter
