Enzyme Catalase Activity in Reaction with the Substrate Hydrogen Peroxide Abstract We performed these experiments to observe the effects of enzymes on the rate of reactions. We tested and compared the activity of the enzyme catalase on the substrate H2O2 in various states and percentages‚ and observed the absorption values of the enzyme-substrate relationship at different concentrations. Our results show that the more substrate available‚ the quicker the reaction will happen except in one test

To prepare a temporary mount of aleaf peel to show stomata. B) Materials required:- Fresh leaves of plant‚ compound microscope‚ glass slides‚ cover slips‚ water‚ glycerine‚ safranine‚ blotting paper‚ needles‚ brush etc. C) Theory :- i) Stomata are minutepore present on the surface of the leaves. ii) Though they are found on both the upper and lower epidermis of the leaf‚ they are more in number on the lower epidermis. iii) Each stoma has two bean shaped

Iso osmolar can be known as the point in which the substance of experimentation faces no change despite the amount of solute inside the solvent( because the solvent and solute concentration is equal. This is where the line on a graph would cross on the

Biomolecules - Biology Unit 3 What is a Biomolecule? Organic molecule made by living organisms Organic Molecules: contain carbon considered the “chemicals of life” Inorganic Molecules: Do not contain carbon Consist mostly of: carbon (c)‚ hydrogen (h)‚ oxygen (o) Monomers vs. Polymers Monomers: single-molecule that may react with similar molecules to form a chain Polymers: a chain of many monomers that are chemically bonded together

______________ Chapter 4 Ecosystems and Communities Section 4–1 The Role of Climate (pages 87–89) This section explains how the greenhouse effect maintains the biosphere’s temperature range. It also describes Earth’s three main climate zones. What Is Climate? (page 87) 1. How is weather different from climate? Weather is the day-to-day condition of Earth’s atmosphere at a particular time and place‚ while climate is the average‚ year-to-year conditions of temperature and precipitation

Investigate the effect of temperature on amylase activity Introduction Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants‚ animals and microorganisms. Large amounts of amylase occur in germinating cereals‚ and in the pancreas and saliva of higher animals. Aim The aim of this experiment is to find out the rate of reaction between amylase and starch in a range of different reaction temperatures. Hypothesis As the reaction

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

Version 2: Identifying Dominant Plant Species 1- Hypothesis Based on the results‚ the bunchberry plant‚ with a scientific name of Cornus canadensis‚ was most frequently seen in station four‚ the ecotone‚ and second most in station five‚ the forest which is most likely in the lower forest since it has a similar environment to that of station four‚ and third most in station three‚ the bog. It was not as frequently seen in areas of higher elevation such as the old field. It should be noted that
