by using the application of membrane have become highly demand in various industries. In this newly separation process ‚ the membrane function as a semi-permeable barrier and the separation process occur by the membrane controlling the rate of movement of various molecules between two liquid phases ‚ two gas phases or a mixture of a gas phase and liquid phase. In industries‚ many companies have high demand on both quality and quantity of water for production. Membrane process can be used to separate

experiment to find the optimum temperature and pH for starch on amylase. The experiment was carried out in one day. The researcher and a partner did the experiment based on a lab manuel from class. Data was collected from the experiment and to be displayed on graphs. Then the optimum pH and temperatures were to be calculated based on the findings. The hypothesis was disproved due to the optimum pH of 5 but the other findings supported the hypothesis of the optimal temperature being 45 degrees Celsius.

Investigate the effect of temperature on amylase activity Introduction Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants‚ animals and microorganisms. Large amounts of amylase occur in germinating cereals‚ and in the pancreas and saliva of higher animals. Aim The aim of this experiment is to find out the rate of reaction between amylase and starch in a range of different reaction temperatures. Hypothesis As the reaction

The effect of Temperature on the Xylem of Tomato Plants Question: How does temperature affect the Xylem in Tomato Plants? Introduction: Throughout this experiment I will be testing the size of the Xylem in Roma tomato plants when exposed to different temperatures. I will be placing six Roma Tomatoes in six different area which will each be in different temperatures. After three weeks of constantly watering the tomato plants with blue dyed water I will cut the plant from the root and examine

Effect of Temperature on Content of Vitamin C Introduction A daily intake of Vitamin C is essential for humans. Without it‚ the disease scurvy develops as sailors‚ explorers and people during the long winters in the Northern hemisphere found before the time of Captain Cook. The British Navy started giving sailors lime juice to prevent scurvy on long voyages in 1795. Vitamin C is found in high levels in foods such as oranges‚ limes‚ lemons‚ blackcurrants‚ parsley and capsicums. Vitamin C is water

INVESTIGATING THE EFFECT OF TEMPERATURE ON THE RATE OF ENZYME ACTIVITY. To investigate the effect that temperature has on enzyme activity I am going to use the enzyme amylase‚ which is used as a biological catalyst to break down starch‚ which cannot pass through the gut wall due to the size of the molecules‚ into smaller ones. Amylase is a carbohydrase‚ which converts starch to simple sugars in the Salivary Glands. Three features of all enzymes are: They are always proteins. They are specific

Temperature Effects on Radish (Raphanus sativus) Root Development Abstract Several studies have been conducted to establish how temperature‚ seed germination‚ and root growth are related. Because temperature plays a main role in many growth processes‚ we decided to focus on how it affected root growth. Radish (Raphanus sativus) seeds were chosen due to their ability to produce a distinct bulbous tuber‚ and their relatively short growing time. Three test groups were placed under different temperature

An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate

The effect of different temperature on the cell respiration. Introduction： Cell respiration is the controlled release of energy from organic compounds in cells to form ATP‚and then release waste products. The process of cell respiration can take place in the presence or absence of oxygen. In either case‚the first stage of cell respiration is glycolysis.The effect of temperature on cell respiration mainly depends on the effect of temperature on of enzyme activity.Generally speaking in a certain

To investigate the effect of temperature on an enzyme controlled reaction Introduction and planning For the investigation of enzymes‚ I am going to conduct an experiment to see how temperature can affect the rate of reaction of enzymes by testing it with starch. The enzyme that we are going to use is called amylase. We are going to test this enzyme with starch. By mixing amylase and starch solutions together under different temperature conditions‚ we can record the rate of reaction by taking a
