out one type of reaction. The catalase enzyme speeds up the breakdown of hydrogen peroxide into oxygen and water. The hydrogen peroxide molecule acts as the substrate molecule and enters the active site where it is broke down into oxygen and water. The oxygen and water then leave the active site.

to be meaning there were at least 2 times to 4 times more water than there should be. The percent yield of oxygen came out to be ‚ around 2%‚ maybe higher considering uncertainty of what amount of oxygen there was suppose to be. The reaction was incomplete and had to be stopped because of time‚ which explains the very high percent yield of the water and the very low percent yield of oxygen. The yield of the catalyst though‚ came out to a perfect ‚ which means that including uncertainty‚ there was

overall health of the water and the surrounding ecosystem. There are many different components that make up a stream’s health. The main factors that affect stream ecology are: geology‚ climate‚ vegetation‚ nutrients‚ bacteria‚ temperature‚ DO (Dissolved oxygen)‚ and toxic chemicals. The shape of the land and the soil is also a big part and can be changed with human activity. The pace of the stream can also change the type of ecosystem that the stream is. Climate plays a major part in stream health. The

When the light hits the tube the leaf discs will produce oxygen gas and float to the top. 4. Oxygen accumulates in the air spaces of the spongy mesophyll‚ and the leaf disk will once again become buoyant and rise in a column of water. Conclusion: 6CO2+6H2O→C6H12O6+6O2. 2.

nitrates into the nearest lakes and rivers. This causes the pollution and contamination of the water. The presence of nitrates in rivers and lakes encourages the growth of algae in the water. The growth of algae will reduce the levels of dissolved oxygen in the water and this poses a problem for the survival of the fish and other living organisms in the water. Denitrifying bacteria helps to metabolize nitrogen compounds using enzymes to release nitrogen gas. This is an anaerobic process and will

Grades K-5 Pencil Electrolysis Introduction: The process by which we separate the elements hydrogen and oxygen from water is called electrolysis. The word "lysis" means to dissolve or break apart‚ so the word "electrolysis" literally means to break something apart (in this case water) using electricity. It is difficult to break up water into it’s elements lots of energy is needed to do that. Through a chemical means though‚ we can separate the compound of water into the elements that combine to

→IMPORTANCE OF FORESTS •Forests play a role indispensable for life on earth by absorbing carbon dioxide and fixing carbon while releasing oxygen into air through Photosynthesis‚ particularly‚ tropical forests absorb almost 2-3 times as much carbon dioxide as temperate forests and have thus been called ‘the lungs of our planet’ •Conservation of water resources •Prevention of disasters •Supplying forest products •Sheltering Rich Ecosystems Wholesome influence of forest on environment:

further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The enzyme that helps with this reaction is called catalase. This is found in both plants and animals. In this lab we will use potatoes as our catalase source. The reaction equation is: Catalase 2H2O2 2H2O + O2 Additional

process. In the first week it turned brown and we believe‚ soapy. So we hanged it out and started fresh. In the beginning‚ it was always murky with low oxygen. We believe it is because our plant life was unhealthy and dying. So‚ therefore‚ it was not performing photosynthesis. We added new plant life and the water became clearer and the oxygen level started to gradually rise. The last week of the project‚ the water started to become cloudy again because the plants were dying. We think all of
