Select the reasons why hexanoic acid releases more energy upon complete combustion to CO2 and H20 a. Since hexanoic acid is more oxidized than glucose, complete oxidation of hexanoic acid generates more reducing equivalents that can enter the respiratory chain. b. Hexanoic acid is more hydrogen rich than glucose, thus hexanoic acid is more reduced than glucose. c. Glucose is more reduced than hexanoic acid, thus complete combustion of glucose requires more energy than the complete combustion of hexanoic acidd. Complete oxidation of hexanoic acid generates more reducing equivalents that can enter the respiratory chain than the complete oxidation of glucose. e. Hexanoic acid is directly broken down into two molecules of acetyl-CoA. However, glucose is first broken down into two molecules of pyruvate, and then converted to acetyl-CoA, thus requiring more energy than the degradation of hexanoic acid.

Dying the folding patterns of protein molecules can microbiologists better understand cellular processes as well as some diseases, such as alzheimer’s, that are caused by proteins that have misfolded. the folding of these complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even expensive supercomputers to do this. a group of researchers at stanford university developed software that can be used to distribute the processing of data to anyone who is willing to donate time on their idle personal computers. as a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done. which statement best describes the work of these researchers? the work is not scientific because the data are not processed in one location. the work is not scientific because the simulations are not reproducible. the researchers applied creativity to solve a problem in running an experiment. the researchers used only well-established scientific techniques.

13. a covalent bond between two atoms is likely to be polar if: a. one of the atoms is much more electronegative than the other. b. the two atoms are equally electronegative. c. the two atoms are of the same element. d. the bond is part of a tetrahedrally shaped molecule. e. one atom is an anion.
