Introduction In the amylase lab‚ it was being tested if amylase‚ an enzyme found in saliva‚ would be denatured by being put in an acid or high temperatures. This lab is about denaturing amylase. It is tested by exposing it to pH and temperature changes. It is then mixed with Benedict’s solution‚ is a solution that changes color from blue to reddish brown when maltose is present. Amylase breaks starch into maltose‚ so is the amylase isn’t denatured‚ it should change colors. Amylase is an enzyme.

lab: To test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function‚ which means having the optimum ph and temperature to catalyze

INVESTIGATING THE EFFECT OF TEMPERATURE ON 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

The role of salivary amylase in the digestion of starches remains controversial. In the absence of pancreatic amylase‚ the key enzyme for starch digestion‚ salivary amylase may well represent a potential compensatory alternate pathway for the digestion of amylose‚ amylopectin‚ and glycogen. Clinically significant depression of pancreatic amylase occurs in chronic pancreatitis‚ pancreatic resection‚ pancreatic neoplasm‚ cystic fibrosis‚ and other causes of pancreatic insufficiency. Quantitation

The Effects of Heat on the pH of the Vegetable and Their Pigment PURPOSE The purpose of this experiment is to see how pH levels of certain vegetables change while being cooked in four different mediums (frying‚ boiling‚ steaming‚ roasting)‚ and how the varying pH levels change the coloring of the vegetables. We will analyze how the different method of cooking/heating changes the levels of pH. BACKGROUND INFORMATION This experiment is based around the different pigments in vegetables‚ of which

The pH Scale is a scale made to show how acidic or alkaline a substance is. The pH of something is measured with pH paper which can vary from wide range paper‚ which covers all ph’s‚ but is not as accurate at some others. There are pH papers that get very specific that can have a range such as 2 or 3 and get much more precise. The neutral on the scale is 7. Anything that is below 7 is considered acidic and anything above 7 is considered alkaline. Acidic substances contain more H+ than OH-. H+

Investigating the Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation‚ you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed

THE EFFECT OF TEMPERATURE ON CATALASE RESEARCH QUESTION: What is the effect of various temperatures‚ 0°C‚ room temperature‚ 37°C‚ 50°C‚ 60°C‚ on the number of oxygen gas bubbles liberated‚ in a decomposition reaction between the enzyme Catalase‚ obtained from crushed mung beans‚ and 2% of the substrate Hydrogen Peroxide? INTRODUCTION: Enzymes are biological catalysts that increase the rate of chemical reactions without they themselves being involved in the reaction itself. Enzymes are proteins

AbstractDifferent pH level may affect the growth and development of the plants. Certain key words include: pH level‚ germination‚ acidity‚ osmosis and diffusion. This experiment examines the effects of different pH level of vinegar on the growth of bean plants. Materials used in this experiment consist of: water (pH 6)‚ vinegar with the pH level of 3‚ 4 and 5 (each one were made before experiment)‚ beans‚ soil‚ and pots. Eight bean plants were planted‚ two were watered with pH 6 and the other ones
