BIOLOGY Representative abundances of selected metabolites found in a small molecule extract (SME) from your designated wild-type bacterial strain are shown in the table below. Note: These reported abundances are dependent on the solubility and ionization characteristics of each compound within this complex mixture. They, therefore, have no direct connection with the metabolite concentrations in […]
In this activity, you will study the effect of pH, temperature and lactose concentration on lactase activity. By the end of this activity, you should be able to: design experiments to study the effects of pH, temperature, and substrate concentration on enzyme activity. graph data related to enzyme activity. analyze data related to enzyme activity. […]
How do enzyme work? POTATO OXIDASE 1. Prepare three clean test tubes. Label test tubes 1 to 3. 2. Pipette 1 mL of catechol solution and small amount of potato extract in tube 1. 3. Pipette 1mL water and a small amount of potato extract in tube 2. 4. Pipette 1 mL of catechol solution […]
1) Find an enzyme that is beneficial to the human race, but is NOT a part of our bodies. Describe it and the reaction it works on. Why is it important to us? 2) Why ATP? – ATP is used by all cells, whether they are from a bacteria or a human being, as a […]
2.1 Explain the lock and key and induced fit hypotheses of enzyme action. 2.2 Explain the role of enzymes in metabolic processes 2.3 Interpret data relating to the effect of temperature, pH or inhibitors on enzyme activity 2.4 Explain the effect of temperature, pH and inhibitors on enzyme activity
Effect of pH on amylase activity There are three parts to this assignment Part One (planning and risk assessment) – about 200 to 300 words The ability of amylase to act as a catalyst enabling the reaction of starch with water (breaking starch molecules down into sugars) depends on the pH of the solution. You […]
