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 in their actions and each enzyme controls

The Effects of Varying pH on Enzyme Activity A lab was conducted to test different pH balances on an enzyme. Introduction: Enzymes are protein catalysts that speed up a chemical reaction without being consumed in the process. Enzymes are three-dimensional structures that consist of one or more polypeptide chains. The polypeptide chains form an active site (where a substrate will fit into). Enzyme molecules are folded into a very specific shape held together by the different forces of attraction

A. 1What are the factors that affect the corn market (i.e. supply curve for corn production and demand curve for corn consumption) ? The corn market can be negatively affected because of the weather and climate have an impact on the supply of the corn. With a bad weather condition‚ like drought‚ the survivability of the corn decreases. The total corn produced the u.s. is facing a large deduce‚ most of the people will be affected. However the corn market can be positively affected. Firstly‚ if

Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

Factors that affect climate Latitude: Ocean Currents: Wind and air masses: Elevation: Relief: Near water: Global Factors that Affect Climate As the suns UV rays hit the earth they hit is directly at the equator causing more heat. Because these rays are direct and they hit direct at one spot. For part a‚ the earth start to slope‚ in which the sun’s rays have to hit a larger areas‚ and have to travel further distances. As the latitude increases‚ the average annual temperatures decreases. In North

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

Effect of Concentration‚ pH and Temperature on Enzyme Activity Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature
