Title: Enzyme Activity Aim: To investigate the activity of the enzyme catalase in liver and potatoes‚ and to investigate the effect of temperature‚ surface area‚ pH and certain chemicals on the activity of catalase. Equipment: Dilute hydrochloric acid solution x 1ml 10 volume hydrogen peroxide x 100ml Copper sulphate solution x 1ml Aluminum nitrate solution x 1ml Zinc nitrate solution x 1ml dilute NaOH solution x 1ml Mortar and pestle x 1 25ml Beaker x 1 Hot plate x1

butterflies need to regulate their body temperatures through thermoregulation. There are two types of ways to regulate body temperature. The first one is ectothermy. Ectothermic animals‚ or cold-blooded animals‚ rely on outside sources to heat or cool themselves. Cold-blooded animals can lie under the hot sun to heat themselves up and prepare for flight or to move around. However‚ if there is no source of heat‚ they are not able to raise their body temperature to the correct level for movement. Butterflies

Packaging has a major impact on the activities performed in a logistical value chain. Packaging can improve or decrease the efficiency of the outbound logistics process. It is therefore important to consider the activities and the value that they add to the overall process. ROL International is a Swedish store interior manufacturer that design‚ produce and distribute their products on a global basis. One of their basic products is the shelf concept. ROL wants to improve their efficiency and consider

RESULTS 28⁰C was the optimal temperature. 28⁰C had the maximum rate of reaction for the class data and results provided by this experiment; the results were represented graphically in graph 1 and graph 2. The reason for having 2 tables and graphs is because 28⁰C was done twice. Data for 28⁰C was collected in this experiment and it was collected again by peers in the classroom. Results are identical because all temperatures except 28⁰C was collected once from peers. Based on the results from the

ACTIVITY SERIES The activity series of metals is an list of metals ranked in order of decreasing reactivity to displace hydrogen gas from water and acid solutions. It can also be used to predict which metals will displace other metals in aqueous solutions. In introductory chemistry‚ the reactivity series or activity series is an empirical series of metals‚ in order of "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water‚ single

Each enzyme has it optimum temperature range at which it functions at an optimum efficiency. In this experiment‚ Rennin might have an optimum temperature of 37 degrees Celsius as it is found in the stomachs of young mammals. As the temperature is increased‚ the rate of reaction (time for milk to curdle) will also increase until the optimum temperature is reached (37 degrees). After reaching this set point‚ the activity of the enzyme will gradually begin to decrease and the rate of reaction will

Antibacterial activity of medicnal plants has turned out to be a global concern. Medicnal plants are very useful in treating various diseases. Antibiotics are an important class of pharmacological agents used for treating antibacterial infections. Although antibiotics were first isolated from fungi and bacteria but over the years more and more synthetic antibiotics has been synthesized‚ which are in great demand. This present study has been done to determine the antibacterial activity of Cannabis sativa

It may be frustrating when a tired person gets into bed and remembers he had forgotten to switch the bed light off. The project ‘automatic night lamp with morning alarm’ helps avoid this problem by switching on an LED itself when it detects darkness in the room. The LED serves as a bed lamp or a reading lamp
