The Effect of pH levels on the Rate of Activity of ⍺-Amylase Ryan Andrew  Introduction: Enzymes are some of the most important chemicals in the human body. Without them, humans and many other organisms would simply be unable to live. Our dependence on enzymes comes from their nature as biological catalysts, substances that speed up chemical reactions without being used up or changed (Worthington-biochem.com, 2017). They allow chemical reactions in our body to occur at a rate that is acceptable

This experiment is being performed to show the effect of pH levels on daphnia by changing pH levels and measuring the heart rate. Introduction Daphnia are used to test water toxicity, they are a vital part of fresh water ecosystems. They are a food source for smaller fish and invertebrates and considered to be a consumer of algae and bacteria (Elbert, 2005). These small crustaceans range in size from 2-5mm long and are commonly referred to as water fleas. Daphnia belong to the group called Daphniidae

The Effect of pH on Enzyme Activity Beginning Question: How does pH affect the rate of enzymatic reactions? Hypothesis: If the pH is around seven, then the rate of the reaction for the enzyme peroxidase will be the highest. This is because the optimal pH range for the enzyme peroxidase is around seven and at its optimal pH an enzyme functions the best. Variables: Independent ─ pH Dependent ─ rate of enzymatic reaction (measured by absorbance) Controlled ─ amount of enzyme used, amount of hydrogen

The Affects of pH on Peroxidase Enzyme Claire Bell Biology 1130 Jazmen Myers Section 36 Abstract Peroxidase is a turnip enzyme; it is used in the oxidation of hydrogen peroxide to lower activation energy, speeding up the reaction. The activity of peroxidase is highly dependent on its environment and most importantly the pH level. Peroxidase has been the focus of many recent studies and is believed to possibly reduce swelling among other things. We conducted an experiment testing

Top ABSTRACT This experiment demonstrates the effects of pH on the rate of photosynthesis by examining the behavior of leaf disks in different pH solutions under light. In this experiment, we used five different pH levels: pH 5, pH 6, pH 7, pH 8 and pH 9. These solutions were created using a combination of hydrochloric acid and sodium hydroxide. Spinancia olcerea or spinach, leaves were used in the experiment to examine the effects of pH on the rate of photosynthesis. The rate of photosynthesis

The practical was carried out to investigate the effect of pH on the reaction of the enzyme acid phosphatase. Of the many functions of proteins, catalysis is by far the most vital. When catalysis is not present, most reactions in the biological systems take place very slowly to produce at an adequate pace for metabolising organism. The catalysts that take this role are called enzymes. Enzymes are the most efficient catalysts; they can enhance rate of reaction by up to 1020 over uncatalysed reactions

Abstract The purpose of this investigation is to discover the effect of pH on the activity of catalase, an enzyme which plays the integral role of converting hydrogen peroxide into water and oxygen, and discover which pH level it will work at the most efficient rate (the optimum). The original hypothesis states that that the optimum would be at a pH is 7, due to the liver, where catalase usually resides, being neutral. The experiment consists of introducing the catalase to hydrogen peroxide, after

Effect of pH on Radish Seed Germination Introduction Germination is affected by many factors including pH. The pH scale is a logarithmic scale that runs from 1 to 14. If the substance ranges from 1-6 it is considered to be on the acidic side, however, if the substance ranges from 8-14 it is considered to be on the basic side. A pH of 7 is neutral, which is typically the pH of pure water. Plants typically have a specific tolerance for pH ranges in which they can flourish. Human activities such as

Effects of pH on Enzyme Concentration Abstract: In this lab report you will be testing the effects pH has on the rate on enzyme reactions, you will be collecting data and evaluating things that went will and ways it could be done better to help us further understand this lab. Research Question: How does pH affect the amount of reactivate when reacted with Hydrogen peroxide on an enzyme? Hypothesis: The higher the pH the higher the reaction with Hydrogen Peroxide on the enzyme will increase. Background

the effect of pH or temperature on enzyme function it is important to consider the type of enzyme being examined. While there may be an apparent effect of pH and temperature on all enzymatic function, the extent of the effect is dependent on the type of enzyme being examined. The current study is focused on the effect of temperature and pH on catechol oxidase; an enzyme that oxidises catechol. The examination of enzymatic activity under the constraints of variable temperature and pH levels are important
