Paragraph 1 – Introduction When I started researching science fair project ideas‚ I came across one that really caught my eye. The driving question‚ or topic‚ was “Does the level of vitamin C change over time in Orange Juice.” After I viewed the website‚ I got very excited because it had simple step-by-step instructions about how to test the level of vitamin C. On the following page are the directions. I think I am really excited to do this project because it sounds very interesting and fun to

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‚

about how changing the pH would affect the denaturation of ovalbumin when cooking meringue. So I decided to add lemon juice to egg whites and heat the egg whites. 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?”

Tropicana’s Orange Juice’s value proposition is that it is heart healthy. It is telling you how it is a delicious way to take care of your heart‚ while providing an excellent source of omega-3 EPA & DHA‚ which promotes cardiovascular health. It also still maintained the fresh-squeezed taste while also providing the great nutritional value it does. As well as that‚ is allows you to enjoy two servings of fruit per serving size as well as an excellent source of Vitamin C. Lastly‚ there is a good

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
