True/False. One reason that proteins as a group show such tremendous structural diversity is that the individual monomers can join together in multiple ways (multiple bond types).

According to the figure of the Redox Tower in the Chemistry Review reading, which of the chemicals in the redox pair is the better electron donor?   CO2/methanol

Would you expect a solution with a pH of 7 or a solution with a pH of 9 to have a lower concentration of hydrogen ions?

What type of monomer is shown in this structure here?

Looking at the figure of the Redox Tower in the Chemistry Review reading, which chemical of the following sets of half reactions is likely to be the best electron acceptor for an energy-yielding redox reaction? FAD/FADH and NAD+/NADH

Looking at the figure of the Redox Tower in the Chemistry Review reading, which chemical of the following sets of half reactions is likely to be the best electron acceptor for an energy-yielding redox reaction? 2H+/H2 and S0/H2S

True/False. Water is a product of a typical polymer condensation reaction.

The SARS-CoV-2 coronavirus that is the cause of the recent global pandemic has an approximate diameter of 75-125 nm.  How is it then that masks and other filtration devices with larger pore sizes (e.g. N95 masks stop most particles larger than 0.3 microns) can be effective at removing virus particles? To answer this question, it would be useful to draw an analogy to the case of Vibrio cholerae and Sari cloth discussed in the reading on microbial size.

Fill in the blank with one of the terms in parentheses. Compared to a smaller cell, a larger cell has (more, less) membrane area per internal cell volume.

Which of these microbial types DO NOT have a nucleus? This is a multiple answer question type, so check all that apply. Note that the grading for this question type will deduct points for incorrectly chosen answers.
