cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Biology Enzymes IA Design Introduction: Enzymes are globular proteins‚ they are responsible for most of the chemical activities of a living organism. They act as catalysts‚ substances that affects the reaction of other substances without being destroyed or altered during the process. They are extremely efficient in the body system of living organisms‚ one enzyme may catalyse over a thousand chemical reactions every second. But there are certain conditions that need to be fulfilled in order for the

The Effect of Enzymes on Apple Juice Production Biology Period 6 Background Info The purpose of this experiment was to determine which enzyme or the combination of the two enzymes makes the most apple juice from applesauce. We did his by‚ mixing 10 drops of an enzyme (cellulose/pectinase/both) into a few tablespoons of applesauce. We then left the rest to nature‚ and watched the liquid funnel out for 10 minutes. Lastly‚ we recorded our data. The cell wall is a complicated

Six Factors Affecting the Performance of an Enzyme Enzymes are considered catalysts; substances that increase the rates of reactions. Enzymes are responsible for thousands of metabolic processes that involve the sustainment of life‚ one common one is simple food digestion. Without enzymes‚ digestion would occur too slowly for life to continue. Enzymes maintain a protein structure consisting of one or possibly more than one polypeptide chains of defined primary structure‚ and take up a characteristic

Hypothesis: the higher the concentration of hydrogen peroxide the faster the reaction will occur and the more foam will be produced. Aim: The aim of this investigation is to determine how the concentration of hydrogen peroxide effects the intensity of the reaction. Variables: Independent- The concentration of hydrogen peroxide. Dependant - The intensity of the reaction. Constants – The temperature‚ the amount of liver‚ pH level‚ test time‚ Materials: Solutions of hydrogen peroxide varying

AN INSIGHT INTO THE WORLD OF CHANDIGARH The City Beautiful Chandigarh is a city and union territory in India that serves as the capital of two states‚ Punjab and Haryana . It is also referred to as The City Beautiful due to its beautiful surroundings‚ central grid of gardens‚ each dedicated to different species of flora. The city of Chandigarh was the first planned city in India and is known internationally for its architecture and urban design. The city has projects designed by architects

they come into contact with atmospheric oxygen. As the pH of solution increases‚ so does the degree of browning of the apple slice. Low pH solutions will cause the enzyme to be inactivated and therefore cause the degree of browning to decrease. As the pH increases so does the degree of browning‚ because the pH becomes closer to the enzymes optimum pH level. Independent Variable: The pH solutions that the apple pieces are placed into. Range of pH levels to be tested is 3‚ 6‚ 8‚ 10‚ and 12. Each solution

FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without
