    Abstract The effect of nature of substrates on the rate of cellular respiration in yeast was determined by using the Smith fermentation tube method. Mixtures of 15ml distilled H2O‚ 10% yeast suspension and 15ml of the following solutions (all at 10% concentration):1- starch‚ 2 – lactose‚ 3 – sucrose‚ 4 – glucose‚ 5 – fructose‚ 6 – distilled water ‚ were poured in six smith fermentation tubes. Cotton balls were plugged in the openings of the tubes and the tubes were kept upright and observed for

    W0Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is a way cells store food and energy‚ a catabolic pathway for the production of adenosine triphosphate (ATP). The cellular respiration happens in both eukaryotic and prokaryotic cells. The three stages are Glycolysis‚ Citric cycle‚ and electron transport. • What is the role

    Lab 8 Cellular Respiration and Fermentation Objectives: 1. Observe the effects of cellular respiration on temperature in a closed system. 2. Investigate carbon dioxide production in both germinating pea seeds and crickets. 3. Perform an investigative study of the rate of cellular respiration in both pea seeds and crickets at various temperatures. 4. Compare the alcoholic fermentation of glucose‚ sucrose‚ and starch by yeast. Introduction All organisms must have a continual

    Cellular Respiration My hypothesis for the germinated pea experiment was that the level of aerobic respiration would increase as the temperature would increase. I also predicted that there would be an upper temperature limit. The experiment proved part of my hypothesis correct and part of it incorrect. I was correct in predicting that the rate would increase as the temperature increase‚ but I was incorrect in hypothesizing that there would be an upper limit. My hypothesis for the larvae experiment

    Cellular Respiration Cellular respiration is a chemical process that produces adenosine triphosphate‚ or otherwise known as ATP for energy that is also needed to survive. It leaves waste products‚ carbon dioxide and water‚ which is needed for photosynthesis‚ a process that only plants use. Production of ATP through the process of cellular respiration occurs in the mitochondria of the cytosol inside plant and animal cells. Cellular respiration occurs in three stages‚ Glycolysis‚ which happens in

    Sarwal AP Lab 4 Determining the rate of Cellular Respiration Using Germinating and Dry Peas Purpose: To determine the rate of cellular respiration using dry and germinating peas. Introduction: In this lab‚ we are investing cellular respiration‚ specifically aerobic cellular respiration. Aerobic cellular respiration is the process by which cells consume oxygen during the oxidation of glucose and produce CO2 as a byproduct. During cellular respiration‚ glucose is split into a 6 carbon sugar‚ G3P
