Diffusion & Cell Size Lab Background The absorption of nutrients‚ excretion of cellular wastes‚ and the exchange of respiratory gasses are life processes which depend upon the efficient transport of substances into‚ out of‚ and throughout living cells. The process of diffusion can be easily visualized by adding a drop of blue food coloring to a glass of water. Initially‚ the food coloring remains in a small area in the water‚ dying it a dark blue. Over time‚ the molecules of food coloring

Identify the appropriate place and promotional strategy that should be used in developing the strategic marketing plan. Consumers rely on having a product in the right place and the right time and it needs to convenient. Time and details goes into finding out what is needed and wanted‚ in addition to what is desired when shopping is needed. Determining the promotional strategy that should be used in the developing the strategic market plan is very important especially how it deals with who the

What is Life? This perennial question the answer to which has somehow eluded the most brilliant minds. For while scientists have identified many years ago the right mix of the atoms and molecules that constitute cellular material‚ they have not succeeded in ‘switching it on’ to make it alive‚ or ‘breathing life’ into it (Rabago et.al‚2006) In this module you will: a. Explain the concepts of the cell theory b. Identify the parts of a cell c. Describe the function of each cell part d. Differentiate

discovered all the time‚ yet all living organisms perform one or both of two very important processes; cellular respiration and photosynthesis. Photosynthesis is performed by plant organisms and some bacteria‚ and cellular respiration is performed by all living organisms. These two processes are reliant on each other. Photosynthesis creates oxygen‚ which is used in cellular respiration. Cellular respiration in turn creates carbon dioxide‚ which is an important “ingredient” in the process of photosynthesis

Cellular Respiration Cellular respiration is basically what cells do to break down sugars into a form that the cell can utilize as energy. Cellular respiration takes in food and uses it to create ATP. ATP is a chemical which the cell uses for energy. The are two forms of cellular respiration‚ aerobic and anaerobic respiration‚ in which will be explained. Regular cellular respiration is aerobic‚ meaning that it requires oxygen‚ but some simple organisms can only do anaerobic cellular respiration‚

Cellular Respiration In this lab the effects of different substrates on the rate of cellular respiration is being put to a test which is a very interesting experiment. The three major substrate solutions being used for this experiment are glucose‚ maltose‚ and alanine. The issues this experiment addresses are cellular respiration occur in different stages which are glycolysis‚ citric acid cycle‚ and fermentation. In this lab the experiment determines the effect of different substrates on

Understanding the function of cellular respiration and fermentation is easy to learn. However it is more difficult to learn the process of glucose being converted into energy. Cellular respiration has four stages‚ of which a phase can consist of eight or ten steps. In the Krebs Cycle alone‚ there are ten steps‚ where the input of Acetyl CoA is eventually reconverted back into oxaloacetate. Fermentation is also no different. It can be difficult for students to understand what the role of NADH

1 Two critical ingredients required for cellular respiration are glucose and oxygen. Cellular Respiration‚ process in which cells produce the energy they need to survive. In cellular respiration‚ cells use oxygen to break down the sugar glucose and store its energy in molecules of adenosine triphosphate (ATP). Cellular respiration is critical for the survival of most organisms because the energy in glucose cannot be used by cells until it is stored in ATP. Cells use ATP to power virtually all of
