〖Na〗^+and K^+channel relationship Figure one shows the temporal relationship between 〖Na〗^+ conductance (g_Na) and K^+ conductance (g_(K )), and the relative changes in the V_m during an action potential. 〖 g〗_Na increased as the V_m moved towards 0 mV causing depolarization of the membrane and started to decrease immediately after the peak of the action potential. Whereas, g_(K ) increased immediately following the action potential peak during the repolarization of the plasma membrane where…

Imagine trying to figure out one possible combination to a mixture, when there are over 100 possibilities. The 8th graders had to look at the physical and chemical properties, to somehow figure out the mixture. A group of students thinks that Baking Soda and Citric Acid is what’s in the mystery mixture. That group thinks that Baking Soda and Citric Acid is in it for a lot of reasons. One reason is that the mystery mixture has circular round objects in it and the Citric Acid is circular and…

Adenosine Triphosphate (ATP) is a nucleic acid present in organisms with the primary function of providing energy. It is comprised of three phosphate groups with one adenosine attached and releases energy by being hydrolysed into Adenosine Diphosphate (ADP), therefore one bond is broken and a phosphate molecule is lost. ATP can only be reproduced through phosphorylation which results in the addition of one phosphate to Adenosine Diphosphate. ATP must be regenerated in order to allow an organism…

Each patient took a urine test and tests were run to see what colour the urine was, this determines how concentrated the urine is. If the urine is darker and has a smell then the urine is more concentrated. If the urine is a light colour and no smell that means it is not as concentrated. Additionally, the urine was tested to determine the pH, glucose, protein, ketone, yeast, blood, nitrite, bilirubin and urobilinogen. Glucose levels are tested in order to test for the plasma levels; if the…

Most enzymes are catalytic proteins made up of amino acids and are a key part of the breakdown and synthesis of virtually every biological catalysis reaction mechanism. The primary function of a catalytic enzyme is to increase the rate of reaction by helping the enzyme overcome the activation energy barrier without the reaction consuming or changing the enzyme. In enzymatic reactions, the substrate binds to the highly specific enzyme active site (the substrate-binding domain) and forms an…

Investigation was carried out to assess the effect of salt concentration on quality of sauerkraut prepared from mature cabbage head. Cabbage sample were chopped in small pieces and mixed with different salt concentrations ie., 2.0, 2.5, 3.0, 3.5 and 4.0 % and allowed to ferment for preparation of sauerkraut at ambient condition. Acidity of sauerkraut increased with increase in fermentation period and it reached maximum on 21 days after fermentation and thereafter it decreased in all the salt…

Protein Casein DCP & CE Hypothesis: Casein is made up of many individual amino acids. Each of them may have positively charge or negative charge depending on the pH of the milk. At certain pH value, positively charges and negatively charges of the casein will equal, so that the number of electrons equals to the number of protons. [1] Approximately pH 4.6 is the pH value that acid casein is precipitated and least soluble. In milk, which has a pH of about 6.6, the casein has a net negative…

Elizabeth Barron Winters July 9th, 2017 Case study 1 Atkins or Fadkins Part 1: Macronutrients and energy Question 1: Proteins: do most of the work in the cells, required for structure, function, and regulation of the bodys tissues and organs. They also transport nutrients and are catalyst. Examples of proteins are nuts, meats, and beans. Carbohydrates: source of energy for the body, simple and complex carbs. Examples are fruits, pasta, sugar, and, grain. Fats: store energy, aid in…

Discussion Graph 1 displays the reaction time (in minutes) of how long it took for the Alka-Seltzer tablet to completely dissolve per trial. Graph 2 displays the averages of the reaction time which showed the higher the water temperature is, the faster the reaction time would be. At 65⁰C the average time for the Alka-Seltzer to completely dissolve was 1 minute 4 seconds followed by 1 minute 20 seconds at 35⁰C and ending with the highest average at 2 minutes 1 second (1.61). The hypothesis…

Question: How does temperature affect the rate of osmosis in raisins? Background: Osmosis is the passage of a solvent through a semipermeable membrane from a less concentrated to a more concentrated solution until both solutions are of the same concentration We designed an experiment that would test if a raisins rate of osmosis is affected by the temperature of water it is placed in. The independent variable in this experiment was time which was 10 minute intervals. The dependent variable…
