Placed 18.6 mL of propanoic acid in a 100ml round-bottomed flask with boiling chips, fit a reflux condenser and brought the acid to reflux. Simultaneously, added .33mL of pyrrole and .47 mL of benzaldehyde through the condenser by using plastic syringes and allowed the mixture to heat under the reflux for 30 minutes.…
The role of glycolysis it to turn glucose molecule into energy by breaking it down in to two three carbon molecules. During this process two molecules of ATP, two molecules of pyruvic acid and two NADH molecules are produced. This process occurs in the ytoplasm of a cell, outside the mitochondrion.…
Stage one glycolysis means the “splitting of sugar”. Glycolysis is a six carbon glucose molecule which is then broken in half, forming two three carbon molecules. The initial split requires an energy investment of two ATP molecules per glucose. Then the three carbon molecules donate high energy electrons to NAD+, the electron carrier forming NADH. Glycolysis then makes four ATP molecules when the enzymes transfer phosphate groups from fuel molecules to ADP. Glycolysis produces a net of two molecules of ATP per molecule of glucose. Then the pyruvic acid holds most of the energy of glucose and that energy is then harvested for stage two.…
1) Glycolysis- the splitting of a 6-carbon glucose molecule into 2 3-carbon pyruvate molecules. There is a net gain of 2 ATP’s produced.…

Glucose, or any carbon-based molecule, can be burned in oxygen (oxidized) to produce carbon dioxide and water. Combustion reactions release large amounts of energy. However, the energy release is uncontrolled. An organism would not be able to handle all that energy at once to do the work of the cell. Cellular respiration is essentially the same reaction as combustion, but the oxidation of glucose occurs in several controlled steps. The same amount of energy is ultimately released, but it is gradually released in small, controlled amounts. High potential energy molecules of ATP are produced while the carbon atoms are used to form various other molecules of lower potential energy. Each of these steps is catalyzed by an enzyme specific to that step. Model 1 illustrates the ideal circumstances for cellular respiration. In some situations, however, one glucose molecule may not result in 38 ATP molecules being…

Jeana Greaves Chem3301-112 June 19, 2013 Synthesis of Aspirin from Methyl Salicylate Introduction The synthesis of Aspirin (Acetyl Salicyclic Acid) began with methyl salicylate and sodium hydroxide as the reagent. The polar oxygen accepts the electrons from now positively charged hydrogen. The positively charged sodium disassociates leaving the hydroxide ion with a negative…
In the first reaction, magnesium was burned to produce magnesium oxide. The reaction produced a bright light, which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles, both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas, hence the other product is magnesium dichloride. In the third reaction, ammonium carbonate was heated to decompose into two gases, due to the absence of anything solid or liquid following the reaction. A wood splint was used to determine that carbon dioxide was present, since the lit splint was extinguished when put in the test tube. Therefore, the other product is ammonium oxide. The fourth reaction occurred between calcium carbonate and hydrochloric acid. When mixed, the two reactants produced a clear aqueous solution, calcium chloride, water, and a gas. The gas was concluded to be carbon dioxide, since the wood splint was extinguished after it was exposed to the gas in the test tube. In the fifth reaction, the two reactants, copper(II) chloride and zinc produced a permanent color change in the solid substance in the aqueous solution. The remaining solid appeared to be black reddish and concluded to be copper, where the aqueous solution is zinc chloride. The six reaction resulted in the formation of a precipitate in an aqueous solution. Copper(II) chloride reacted with sodium phosphate to produce a fluffy blue solid, copper(II)…
Cancer known in medicine as a malignant neoplasm is one of the biggest killers worldwide. In 2007, cancer caused roughly 13% (7.9 million) of the planet’s deaths (Jemal, 2011). This will more greatly affect an aging society such as ours in years to come, and yet it is already the foremost cause of death in the developed world. The main reason cancer causes so many fatalities the body’s inability to mount an effective response to the failure of DNA replication within the body. This results in a mass of uncontrolled tissue proliferation which eventually leads to death. Approximately, 50% of all people who get cancer will eventually succumb to the disease (Jemal, 2011). It is therefore essential that new methods for controlling the disease are found to improve the prognosis of suffers.…

Adoption is an extremely sensitive subject,(insert dash) especially for individuals who are Gay or Lesbian. There is much controversy on the topic. There are a variety of ways to which it isn’t possible for a couple to adopt. Infertility is becoming a greater problem in our time. In Gerald P. Mallon’s article, “Assessing Lesbian and Gay Prospective Foster and Adoptive Families: A Focus on the Home Study Process,” in 2007. He introduces a few different ways gay men and lesbian couples go about starting a family and mentions how the decision to adopt or become a foster parent for a child is a huge step in parenting. There are even more studies today that show, gay men and lesbians make good parents. In Scott Weber’s article, “Nursing Care of Families with Parents who are Lesbian, Gay, Bisexual, or Transgender,” he brings to attention, what the child may experience growing up in such circumstances. Some things a child may experience are teasing and sensitivity to being harassed. Both articles have valid arguments on the topic of gay men and lesbian headed families. Mallon argues how lesbians and gay men are potential parents for many children and youth who need permanent families while Webber argues children of non heterosexual couples are more likely to be teased and sensitive to being harassed.…
