5. Explain why direct antigen activation of CTLs and B cells is more important than APC-initiated activa- tion in subsequent encounters with a microbe. Why is the APC-initiated pathway needed at all? 6. There are many interactions between the innate and adaptive defense systems. List as many of them as you can and explain how they work. Why are these interactions important? Are all of them beneficial? 7. What are the two ways that polysaccharides, DNA, and lipid antigens can...

1. What is a structure based explanation for why acetamide is
more stable than acetone. I'm pretty sure it has to do with
resonance.
2. also for question F im fairly sure it has to do with
resonance again but I not sure exactly why. could someone answer
and explain?
F. Draw the conjugate base for each compound below and draw the appropriate structures to explain the difference in N-H acidity pKa~9.5 pKa 16 N-H N-H

1a) Electrons in an atom are more stable than free electrons. This is why the energy levels of electrons in atoms are negative (free electrons are defined as having an energy of zera). Calculate the energy of a hydrogen. electron in the 4" shell, in J. b) Calculate this energy in kl/mole. 2. Calculate the energy for nu1, 2, 3, and 5 as well. Graph these energy levels in Joules, including n-5, in your lab...

Could anyone explain why the first compound is more stable than
the one I circled? And also, why is resonance a stronger influence
and not induction? Thanks!
