To write:

How cytomegalovirus subverts the ability of NK cell receptors to mediate immune responses.

Introduction:

NK cells are key modulators of immunity as they are involved in cytotoxicity. They are most important in viral infections as they produce interferon gamma (IFN-γ) against the viruses. They are said to holds some properties involving memory towards viral antigens which provides some degree of passive immunity. The cytomegalovirus downregulates NK cell receptors involved in the activation of NK cells.

8. Aerobic respiration of a 5 mM solution of tripeptide that is composed of the following three amino acids; alanine, leucine and isoleucine. Alanine breaks down to pyruvate, leucine breaks down to Acetyl-CoA and isoleucine breaks down to succinyl-CoA. Alanine NADH FADH2 OP ATP SLP ATP Total ATP Leucine Isoleucine Totals Show your work using dimensional analysis here: 4

9. Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. fatty acids glycerol 18 carbons 12 carbons 0=
