Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase‚ during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic

Lab Report: Enzyme Lab Your Name: Samantha Butcher Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? It is going to explain how a liver’s enzymes break down substances that could be harmful.| Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. Give your reasons and outline any assumptions that lead

structures of cells but they act as enzymes in reactions of the body1. Enzymes are biological catalysts that lower the amount of activation energy needed in carrying out biochemical reactions1. Enzymes are responsible for almost every reaction that occurs in a cell and is named according to the substrate they specifically affect. An enzyme works best under optimal conditions pertaining to temperature‚ pH level and salt concentration1. In unfavorable conditions enzymes will become denatured and ineffective

Enzyme Catalysis Lab Problem: Before the lab‚ one should understand: • The general functions and activities of enzymes; • The relationship between the structure and function of enzymes • The concept of initial reaction rates of enzymes; • How the concept of free energy relates to enzyme activity; • That change in temperature‚ pH‚ enzyme concentration‚ and substrate concentration can affect the initial reaction rates of enzyme-catalyzed reactions; and • Catalyst‚ catalysis‚ and catalase

In my investigation I am going to establish the effect of changing light intensity on the rate of photosynthesis. What is Photosynthesis? Photosynthesis is how plants get their food. The reason why plants have leaves‚ roots or being green is all linked to photosynthesis. In photosynthesis‚ a plant takes carbon dioxide from the air and water from the soil and uses the light from sunlight to turn them into food. Photosynthesis occurs only in the presence of light‚ and takes place in the chloroplasts

EFFECTS OF GEOGRAPHICS AND RECYCLING 1 Effects of Geographic Location and Recycling Participation. EFFECTS OF GEOGRAPHICS AND RECYCLING Abstract Research was conducted to determine if recycling participation is affected based on where an individual lives and/or where they grew up. Many psychological and sociological studies have looked into the human behavior of recycling; what drives an individual to recycle and what are the key components to a successful recycling program. Results have

Factors Affecting The rate of Enzyme Activity Prediction: As the temperature increases the rate of enzyme activity will also increase‚ thus increasing the rate of reaction. However‚ if the temperature is too high the enzyme will denature.

Enzyme Immobilization Methods Covalent Binding: Covalent binding is a conventional method for immobilization; it can be achieved by direct attachment with the enzyme and the material through the covalent linkage [37]. The covalent linkage is strong and stable and the support material of enzymes includes polyacrylamide‚ porous glass‚ agarose and porous silica [38]. Covalent method of immobilization is mainly used when a reaction process does not require enzyme in the product‚ this is the criteria

Effect of Cohabitation on the Rising Divorce Rate The rise of the divorce rate seems to be due to the lack of commitment or understanding of love and longevity in a marriage. Cohabitation can be defined as an arrangement whereby two people decide to live together on a long term or permanent basis in an emotionally and /or sexually intimate relationship (Brannon 2008). Cohabitation is seen as the best way to understand a prospective mate in terms of living and financial stability
