How many carbons are in a molecule of glucose? 6 4. The energy related during these oxydation reactions is used to form adenosine triphosphate ( ATP )‚ the Energy currency of the cell. 5. Name the two initials steps in glycolysis. The initial steps are the additions of two phospates to the glucose molecule at the expense of two molecules of ATP. 6. What are the three molecules that results? The three molecules that result are a 6 carbon

* Aerobic respiration requires oxygen and produces CO2‚ water and lots of ATP. * Aerobic has 4 stages: 1) Glycolysis – the splitting of the 6-carbon glucose molecule into 2 3-carbon molecule pyruvate molecules. 2) Link reaction – the conversion of the 3-carbon pyruvate molecule into CO2 and a 2-carbon molecule called acetylcoenzyme A. 3) Krebs cycle – the introduction of acetylcoenzyme A into a cycle of oxidation-reduction reactions that yield some ATP and a large number of

Intermolecular forces that affect the molecules shape and composition will directly affect the viscosity of the molecule. An example of this can be observed between ethyl alcohol and ethyl glycol. Ethyl glycol has two more O-H groups than ethyl alcohol. The extra O-H groups effect the amount of hydrogen bonds in the ethyl glycol molecule. The ethyl glycol has more hydrogen bonds than ethyl alcohol. This gives the ethyl glycol molecule a higher viscosity than the ethyl alcohol molecule. Both kinetic energy and

mitochondrial matrix and its main function is to turn the pyruvate into acetate for the kerb cycle. During the link reaction the pyruvate molecule undergoes decarboxylation and dehydrogenation‚ the enzymes pyruvate decarboxylase and pyruvate dehydrogenase remove the carboxyl group (which becomes a carbon dioxide molecule) and removes the hydrogen atoms from the pyruvate molecule. The coenzyme NAD accepts the two hydrogen atoms and becomes reduced NADH2 and the coenzyme-A accepts the acetyl (from pyruvate)

I will compare how these two sets of molecules react in colder temperatures; then hotter temperatures; and how the two react with each other. Then‚ based on these findings‚ I will offer theories of two case studies involving 1) honey added to two cups of tea and 2) a package of smelly limburger cheese opened on a winter and summer day. The experiment begins with a chamber that is divided—on the left are 20 red molecules‚ on the
