Which of the following elements is NOT a heteroatom? carbon nitrogen phosphorous sulfur oxygen
Draw a diagram of cellular respiration. Use closed arrows ( to trace the carbon atoms, and open arrows (=) to trace ATP / ADP and electron carriers (and their oxidized counterparts) through glycolysis, pyruvate oxidation, and the Krebs cycle. Draw a box around the stage(s) that take place in the cytosol and a circle around the stage(s) that take place in the mitochondrion. For full credit indicate the number of each of the inputs and outputs for each stage of...
One major difference between the carbon, nitrogen, and sulfur cycles compared to the phosphorous, calcium and silica cycles is that the P. Ca, and Si cycles are NOT affected by global warming or other human activity the R. Ca, and Sicycles do NOT involve redox changes or gaseous forms that can alter Earth's atmospheric chemistry . Ca and Si are NOT cycled in terrestrial environments. the R. Ca and Sicycles do NOT involve microbial activity
2) Draw and label a diagram of the carbon cycle. See Figure 4-3 for an example. Show the important reservoirs and indicate an approximate size (give units) of the reservoirs. Label arrows to depict the pathways that carbon takes through the various reservoirs (I don't expect you to list or memorize all the flux rates, but you should know which ones are important at different time scales). Then, below your diagram, list the carbon pathways that are most involved in...
Describe how human activity is altering the carbon cycle and the nitrogen cycle? What ecosystem service is this alteration disrupting?
Draw 3 molecules that could exist in nature using the atoms: Carbon (C), Nitrogen (N), Hydrogen (H), and Oxygen (O). Each molecule must contain at least 3 carbon atoms and 1 oxygen atom. Must follow atom specific covalent bonding requirements ( C=4 ; N = 3; O =2; H =1).
Diazomethane is an organic compound with molecular formula CH2N2. Draw the Lewis dot structure for this compound. Calculate the formal charges on the carbon and nitrogen atoms. Draw a resonance structure for this compound, using arrows to indicate flow of electrons. Are the two resonance structures identical? If not, indicate the major and minor contributors giving suitable explanation.
Draw a large labelled diagram to illustrate the main features of the nitrogen cycle.
Draw reaction mechanism using arrows. Please indicate nucleophile, electrophile, products, show intermediate structure and name (please show which carbon carriers charges if possible), if anti/syn chemistry is involved, please indicate “anti” or “syn” at the end of the reaction equation. Please name the product. Please indicate “follow Markovnikov’s rule” or “not follow Markovnikov’s rule”. (If hydride shift is possible, please consider it and show it in your reaction) 1) pent-1-ene ( or 1-methylcyclohexene) reacts with Br2
