are organic molecules and capture in their ATP. Some of these organisms need oxygen to do this but not all of them require it. Organic carbon molecules are the energy source‚ and for waste is carbon dioxide (CO2) and water (H2O). CO2 can combine with water to form carbonic acid during cellular respiration. Phenolphthalein can be used to help detect any changes in pH because of production of CO2 during cellular respiration. Phenolphthalein usually appears clear or colorless in acidic solutions‚ and

This scientific report will be based on cellular respiration‚ or fermentation. In specific‚ how the type of sugar affects the rate of fermentation. The aim of this experiment was to find which type of sugar was best suited to produce ethanol. In the experiment‚ four different sugars were used‚ they included sucrose‚ glucose‚ lactose and fructose. This research is still relevant today‚ as alcohol is still consumed and is required on a large scale. This makes it crucial to companies to find the best

list of items‚ both tangible and non tangible‚ that trees give us. First of all‚ as we all know‚ trees are the most important and the only natural source of oxygen in the atmosphere. Without oxygen[->0]‚ life is not possible on earth. Trees consume the carbon dioxide[->1] from the environment and give out oxygen which balances the amount of oxygen and carbon dioxide[->2] in the atmosphere. In addition to this‚ the wood that we obtain from trees is used in making paper‚ building houses‚ making furniture[->3]

Extractive Metallurgy Minerals are naturally occurring chemical substances in the earth’s crust obtainable by mining. Out of many minerals in which a metal may be found‚ only a few are viable to be used as sources of that metal. Such minerals are known as ores. Examples: Galena‚ PbS‚ etc. It is usually contaminated with earthly or undesired materials known as gangue. The extraction and isolation of metals from ores involve the following major steps: • Concentration of the ore‚ • Isolation of the

waters‚ such as lakes and streams. Phosphates are essential to aquatic plant growth‚ but too much phosphate can lead to the growth of algae and results in an algae bloom. Too much algae can cause a decrease in the amount in dissolved oxygen in the water. Oxygen in water is affected in many different ways by phosphates Phosphorus is usually present in natural waters as phosphate(Mcwelsh and Raintree‚ 1998). Phosphates are present in fertilizers and laundry detergents and can enter the water from

Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods

Cellular Respiration and Photosynthesis Photosynthesis is the process by which plants‚ some bacteria‚ and some protistans use the energy from sunlight to produce sugar‚ which cellular respiration converts into ATP‚ the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy‚ is associated with the actions of the green pigment chlorophyll. Most of the time‚ the photosynthetic process uses water and releases the oxygen. Cellular respiration
