Cellular Respiration is part of the metabolism of organisms‚ it provides the energy for organisms’ basic life activity. The process of cellular respiration converts oxygen and water to glucose and carbon dioxide‚ and usually occurs inside of mitochondria. Thus the cellular respiration is closely related to the life of all organisms‚ especially the human. In a case study in cellular respiration‚ seven unrelated people died in five days‚ and the reason is unclear. However‚ all the victim had same

Cellular Respiration OVERALL EQUATION: C6H12O6(aq) + 6O2(g) -> 6CO2(g) + 6H2O(l) 3 OVERALL GOALS: 1. Break bonds between the 6-carbon molecules of glucose – results in 6 CO2 molecules 2. Move hydrogen atom electrons from glucose to O2‚ forms 6 H2O molecules 3. Trap as much free energy released as possible in the form of ATP Stage 1: Glycolysis Cytoplasm‚ 10 reactions‚ anaerobic Stage 2: Pyruvate Oxidation Mitochondrial matrix‚ 1 step process Stage 3: The Krebs Cycle Mitochondrial

“Investigate how light and darkness contribute to the cycling of carbon through both cellular respiration and photosynthesis of a plant” we devised a hypothesis that states‚ If we place the two test tube‚ one with carbonated water and the other regular water‚ with the Elodea inside a dark environment it will perform cellular respiration as it will not receive enough light energy to perform photosynthesis. From the result of our experiment we found that the test tube with tap water and Elodea changed

PHOTOSYNTHESIS LAB Alyssa Wright VARIABLE: LIGHT INTENSITY AIM: to investigate the effect of light intensity (lux) on the amount of oxygen produced (number of bubbles) HYPOTHESIS: I predict that the rate of oxygen produced increases‚ as the light intensity increases‚ but only to a point. I predict this will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen

Goldfish Respiration Abstract The purpose of this experiment is to design and conduct a basic scientific experiment‚ identify and control variables. Some other objectives that we learned is to write a formal hypothesis‚ identify the basic and integrated process skills of science that were used in this experiment. Also‚ we will learned the effects of temperature on goldfish respiration. This experiment will be conducted with four students ‚ one goldfish‚ thermometer‚ a stop watch‚ and a beaker

Photosynthesis is a form of a chemical reaction that transforms energy from the sun in to a chemical energy‚ a carbohydrate known as glucose. Only plants are able to use this process to make their own food. This chemical reaction takes place in Chloroplasts‚ cells that are found in any green part of the plant. Chloroplasts are in green fragments of the plants because it contains a green pigment called chlorophyll. Although Photosynthesis can occur in any green portion of a plant‚ it mostly occurs

possible by my AP Biology teacher’s assignment. If not for her‚ I would never have sat down and composed a four page script about Photosynthesis. I would also like to thank my supporting family for listening to my complaints and frustrations throughout this process. My gratitude goes out to the AP Bio Facebook group as well‚ for answering all the questions I had about Photosynthesis. Thank you all very much.

How does photosynthesis model the Law of Conservation of Matter and The Law of Conservation of Energy? Photosynthesis models the Law of Conservation of Matter and the Law of Conservation of Energy‚ and there is evidence from some articles that were read to prove this statement. First‚ the Law of Conservation of Matter is modeled in photosynthesis‚ because in the Photosynthesis for Kids article it stated‚”Photosynthesis occurs when Chlorophyll‚ a green pigment that collects lights‚ consumes radiant

ABSTRACT The effect of co-factor (MgSO₄) and the nature of substrate on the rate of cellular respiration in yeast were determined using two different set-ups. In the first set-up‚ two test tubes were used where one contains 7m and the other with 7 mL 0.2M MgSO₄ and both containing 7mL 10% yeast suspension. Here‚ data shows that the H₂O mixture showed higher amount of CO₂ evolved than MgSO₄. In the second set-up‚ six Smith fermentation tubes were used each containing different 15mL solution (starch
