Background Research Yeast are eukaryotic microorganisms just like other organisms‚ they must respire in order to survive. Respiration can be defined as the controlled release of energy from organic compounds to form adenosine triphosphate (ATP). The type of respiration that occurs is called aerobic respiration. It occurs when glucose and oxygen are present. It can be summarized by the equation: . Enzymes play a very significant part in respiration. During the different stages of respiration‚ enzymes

“taking energy from the steadily blowing wind” (Crowell). Eventually enough of these energetic vibrations built up to cause resonance within the system‚ causing the wave-like motion of the bridge. Energetic vibrations can be explained by using the example of a mass on a spring where potential and kinetic energy are involved. This system can be put into motion by “hitting the mass to put in kinetic energy or by pulling it to one side to put in potential energy” (Crowell) and will continue in this motion

without using water molecules to act as ’scaffolding’ within the structure CuSO4.5H2O. When this is heated the water molecules are driven off and the blue crystals become a white powder. As most crystals are made by evaporation from an aqueous solution‚ it makes sense that water molecules can incorporate themselves into the ionic crystal structure. Water‚ after all‚ has an oxygen atom with two lone pairs capable of behaving as a Lewis base; it bonds easily to metal ions as evidenced by complex
