Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

In this study‚ three general media will be used for the detection of microorganisms on the equipment‚ personnel‚ raw materials and the finished goods. These are Potato Dextrose Agar (PDA)‚ Plate Count Agar (PCA) and Violet Red Bile Agar (VRBA) under the Univar brand. The amount of each prepared medium or dehydrated medium depends on the number of samples to be tested. PDA is usually used for the presence of yeasts

Aim To investigate the effects of increasing salinity on potato cell mass. Background Information This experiment is based upon osmosis. Osmosis can be defined as the net movement of water molecules from a region with high concentration to a region with low concentration. This movement must take place across a partially permeable membrane such as a cell wall‚ which lets smaller molecules such as water through but does not allow bigger molecules to pass through. This process will take place until

Comparisons between The Hispanic Migration to the United States & the Irish Potato Famine The Irish Potato Famine and The Hispanic Migration are completely different things that happened at 2 different times‚ but there are some things that are similar. The push and pull factors of these 2 migrations are the environmental‚ social‚ and political reasons. These reasons are very important when it comes to leaving or going to a new country or place. The environment of Mexico is very rough and very

Look again at ‘At a Potato Digging’ by Seamus Heaney and at ‘A Sheep Fair’ by Thomas Hardy‚ which both deal with the theme of the hardship of rural life. With close reference to the ways each poet uses language‚ compare and contrast what the speakers in the poems say about rural life. You should include relevant contextual material. Which poem do you find more interesting? Give your reasons. Seamus Heaney and Thomas Hardy both depict images of rural life as difficult and uncomfortable. In their

Mass each bag. Put each bag into a beaker of distilled water and let stand for half and hour. After 30 minutes is up‚ remove each bag and determine its mass. Record all data in its appropriate table. Lab 1C - using the potato core borer‚ obtain 24 cylindrical slices of potato‚ four for each cup. Determine the mass of the four cylinders. Immerse four cylinders into each of the six beakers or cups. Let stand overnight. After time is up‚ remove the cores from the sucrose solutions and mass them

The article‚ “You say Potato‚ I say Electricity‚” focuses mainly on water‚ potatoes‚ and the energy crisis. A lot of water is being used for potatoes. Due to improvements in technology‚ Idaho farmers 20 billion pounds of potatoes‚ which is‚ “up from 12 billion pounds 20 years ago.” This causes a partial shift in the Production Possibilities Curve (PPC). There is a surplus of potatoes because the market supply is a lot more than the market demand. When using a lot of the water on potatoes‚ hydroelectric

the effect of sugar on the mass of potato Introduction- diffusion is a passive transport where molecules move from areas of higher concentration to areas of low concentrations. Although the molecule ’s movement is random‚ equilibrium is being sought out. Osmosis is a type of diffusion only It involves water. In osmosis water diffuses from the area of high concentration to an area of low concentration‚ to diffuse the more molecule rich side. Because cells have selectively permeable membranes‚ meaning

GCSE - Human Physiology and Health An experiment to investigate what affect sucrose solution has on potato tissue. Background Osmosis is the movement of water molecules‚ across a partially permeable membrane from a region of high concentration of water to a low concentration of water molecules. A partially permeable membrane is a membrane with holes in it small enough for only water to go through it. Big molecules like glucose cannot fit through it. Osmosis allows plants to take in water
