12. Briefly discuss the role of the electron transport chain in cellular respiration. In your explanation‚ discuss and identify key molecules involved in this process and explain their relationship which each other in terms of how they contribute to the main cellular purpose of this process. Electron transport chain plays a key role of in the production of oxygen in cellular respiration. ETC uses many enzymes located on the inner mitochondrial membrane during the production of oxygen.

Abstract: In this Lab we used the chemical DPIP to detect the rate of succinate broken down by the mitochondrial solution. We detected the amount of DPIP in the solution with a spectrophotometer and measuring the absorbance of light at the 600nm range. DPIP is a useful chemical to use in this experiment because it goes from a blue color when oxidized to a colorless liquid (Ogura‚ 281)‚ this is due to the hydrogen ions and electrons released during the transitional step between succinate and fumarate

Every physical action we take requires some sort of energy that our body produces. The most important energy molecule in the cell that our body uses is adenosine triphosphate (ATP). ATP is “a high-energy molecule that stores a considerable amount of energy within the chemical bonds that hold the molecule together” (Exercise Physiology: Tennis Physiology). ATP results from energy being produced from either an aerobic system or anaerobic system. The production of ATP can come from systems such as ATP-PC

After reviewing the case study and each individual‚ I was able to distinguish a few similarities between their deaths. The symptoms that most patient’s exhibited were a headache‚ confusion‚ shortness of breath or rapid breathing‚ dizziness‚ and vomiting (Gazdik‚ 2010). Another similarity between the individuals was that most of their deaths occurred within a few hours of their symptoms and were very rapid (Gazdik‚ 2010). A connection between the seven individuals is that they all resided in the same

Carbohydrates come in a variety of sizes. Describe the basic chemical structure of carbohydrates and explain how larger ones are made. How do the category names of different carbohydrates relate to the complexity? Finally‚ what are they used for in organisms? Carbohydrates are made by the basic chemical structure of Carbon‚ Hydrogen‚ and Oxygen‚ in the same two to one ratio that makes up water. It is made bigger when an enzyme comes in and takes hydrogen and oxygen away from two different

got to test the chemical properties they saw a better idea of what it could be or not. Then the eighth grade scientist got to test the temperature of the chemical reaction and by that time it was clear what it was. The students think that it is Citric Acid and Baking Soda. They think it is that because when you look at the physical properties of Baking Soda you can see that has clumpy and had some big pieces which would be like the clumps in the Mystery Mixture. Another thing that Baking Soda has

natural acid‚ citric acid industry has seen a fast growth in China before 2008 due to increasing demand from both of overseas market and domestic market. However‚ in the past five years‚ China’’s Citric Acid production has been expanding slowly due to demand increase very slowly. What’’s more‚ the price of citric acid’s raw material witnessed the uptrend in the same period. What has happened in the citric market in past five years? How is the current competition structure of citric acid in China

The citric acid in the lemon juice would lower the pH of the egg whites. I tried to find the answer to the question‚ “How does citric acid affect the denaturation of the protein ovalbumin in egg whites by heat?”

Title Abstract During this experiment the change in pH of Citric acids is measured from start to equilibrium in mL. This experiment was tested by titration it had two separate trials. Through observations it was shown that the more concentrated acids needed more drops of NaOH to reach its equilibrium then the less concentrated acids. Introduction Sodium Hydroxide (NaOH) is a strong base and when it is titrated with a strong acid the equivalence point will be expected to be a pH of 7 (wyzant
