The Role of the Citric Acid Cycle The Citric Acid Cycle is a series of enzyme-catalysed reactions that take place in the mitochondrial matrix of all aerobic organisms. It involves the oxidation of the acetyl group of acetyl CoA to two molecules of carbon dioxide. Each cycle produces one molecule of ATP by substrate-level phosphorylation‚ and reduces three molecules of NAD and one molecule of FAD for use in Oxidative Phosphorylation. The cycle is preceded by Glycolysis‚ which also occurs in anaerobic

Title : The Vitamin C content of fruit juice Aim : To investigate the vitamin C content of fruit juice. Introduction : [2]Vitamin C‚ also known as the ascorbic acid or the L-ascorbate‚ is required for the growth and repair of tissues in all parts of our body. It is necessary to form collagen‚ an important protein used to make skin‚ scar tissue‚ tendons‚ ligaments‚ and blood vessels. Vitamin C is essential for the healing of wounds as well as for the repair and maintenance of cartilage‚ bones

Describe the role of the citric acid cycle as a central metabolic mechanism. Explain what happens to the cells’ abilities to oxidize acetyl CoA when intermediates of the cycle are drained off for amino acid biosynthesis. Glucose is a source of energy that is metabolized into glycolysis to pyruvate yielding ATP. To become more efficient‚ pyruvate must be oxidized into carbon dioxide and water. This combustion of carbon dioxide and water to generate ATP is called cellular respiration (Tymoczko‚

drink or orange juice. Which has had me to do the orange juice vs. sports drink experiment. The reason why I aminterested in this topic is because for the long time I have loved the flavor of these drinks. But ever since I have been working out I’ve been wondering which drink is most beneficial when working out or participating in any physical activities that would get you tired. Because when I have to chose a work out drink I don’t know if I should choose my favorite juice that is orange juice

2015 Titration Lab 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

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
