Cellular Respiration Purpose The purpose of this experiment was to determine the effect of body mass and temperature on the rate of respiration in the mouse. Hypothesis When the temperature is reduced‚ cellular respiration will increase. Measurement Weight the mouse and use soda lime for mouse to perspire. Oxygen was inhaled and carbon dioxide was exhaled. Carbon dioxide was absorbed by soda lime. Rate of respiration was measured in terms of ml of oxygen per min over grams. General

An Increase in Light Intensity Increases the Rate of Respiration M. Chauntise‚ S. Shaika‚ R. Shantal INTRODUCTION The sun plays a vital role in sustaining an entire living world whether indirectly or directy using a transformation process called photosynthesis. This process assists in nourishing plants and keeping them alive. For example‚ trees grow very tall in the rainforest where there is an abundance of water in order to reach as much light as they can. For this reason‚ in order to survive the

membrane. It always navigates to the area of the membrane with a higher solute concentration. We take a closer look at the effects of osmosis in this lab through the examination of red blood cells (sheep)‚ plant cells (elodea)‚ and active transport in yeast. Under the microscope‚ we can determine the effects on plant and animal cells exposed to hypotonic‚ hypertonic‚ and isotonic sodium chloride solutions. Plant cells have a cell wall; however‚ animal cells do not. This is examined as a major difference

Living things get energy to do things through photosynthesis‚ food molecule breakdown‚ build up‚ storage‚ and lastly cellular respiration. All of these ideas are the reason that myself and others have energy to do anything and everything. Photosynthesis is one way plants(plants are the main source of energy for all things)get energy to do things. The reactants of this are water‚ carbon dioxide‚ and although light energy is not a reactant‚ it is necessary once the energy from the seed is gone. Carbon

inorganic cofactor such as Magnesium to the rate of respiration of yeast was determined using Durham tube assembly with the substrate glucose. After thirty minutes‚ the test tube with the cofactor in the form of Magnesium sulphate MgSO4 showed the higher amount of carbon dioxide evolved which was measurable through volume and was one of the by- products of cellular respiration. This stated that the higher amount of CO2 evolved‚ the higher the rate of respiration. Thus‚ the hypothesis “If enzymes need cofactors

data. As evident in the table‚ the 10oC temperature is very accurate as the range was 0‚ resulting in an error percentage of 0%. However‚ the 35oC temperature had a no clear skew of results as indicated through the range‚ 14 and the error percentage‚ 161.47%‚ suggesting that the trials at this temperature were not very accurate as they were largely inconsistent. The 50oC also proved to have inaccuracies‚ however‚ not as significant as the previous temperature‚

Temperature and Thermometers The Temperature of an object is a measure of the hotness or coldness of that object. An alternative way to think of temperature is to say that “the temperature of an object is a number – on some manmade scale – that indicates the hotness of the object”. ‘Hotness’ in turn is a measure of the kinetic energy of the molecules of the material. Note: You must use the term ‘hotness’.* The SI unit of temperature is the Kelvin (K)* Relationship between degrees Celsius
