The excerpts below were obtained from a 2022 Journal of Biological Chemistry publication called “Structural basis for the in vitro efficacy of nirmatrelvir against SARS-CoV-2 variants”. The paper reports that Omicron P132H mutations leave nirmatrelvir potency largely unchanged. What structural rationale is most consistent with this finding?

  What is a common potential side effect of Rimadyl/carprofen?

The information below is an excerpt from a 2025 publication in Nature titled “Structural and functional characterization of human sweet taste receptor”. Certain T1R2 VFT mutations shift EC50 values for multiple sugars in parallel. What structure–function conclusion is most consistent with this pattern?

The excerpts below were obtained from a 2022 Journal of Biological Chemistry publication called “Structural basis for the in vitro efficacy of nirmatrelvir against SARS-CoV-2 variants”. In Figure 2, nitrogen atoms are colored blue, sulfur atoms are colored yellow, and oxygen atoms are colored red. Nirmatrelvir is known to form a reversible covalent bond to Cys 145. What is the side chain of Cys that is involved in the formation of the covalent bond?

As the biological levels are listed from least inclusive (specific) to most inclusive (broad), what is the level after “organism”? Remember this is going from the most specific to the least specific (most broad) category. 

Assume that the consumption function is given by C = 200 + 0.7 (Y − T), the tax function is given by T = 100 + t1Y, and Y = 50K0.5L0.5, where K = 100 and L = 100. If t1 increases from 0.2 to 0.25, then consumption decreases by:  

The figure below is an excerpt taken from a paper titled “Chain Length-dependent Binding of Fatty Acid Anions to Human Serum Albumin Studied by Site-directed Mutagenesis”, published in 2006 in the Journal of Molecular Biology. Human serum albumin (HSA) is the most abundant plasma protein and a versatile carrier that transports a wide range of ligands. It binds long‑chain fatty acids at multiple high‑affinity sites located across distinct protein subdomains, using hydrophobic pockets and specific hydrogen‑bond/ionic interactions to stabilize the anionic carboxylate headgroups. By buffering and distributing fatty acids between tissues, HSA modulates their bioavailability, prevents micelle formation and toxicity in plasma, and delivers them to cells via reversible, concentration‑dependent binding. The graphs presented in Figure 1 compare the binding of 4 different fatty acids of varying length (octanoate = 8 carbons, decanoate = 10 carbons, laurate = 12 carbons, myristate = 14 carbons in length) to the wildtype HSA and to a mutant HSA they created in the lab (denoted as R410A, which indicates that the amino acid at position 410 in the wildtype protein is normally an R but the researchers intentionally changed it to an A). Finish the following sentence: “Based upon the plots, the fatty acids bind ____ to the recombinant mutant HSA than they bind to the wildtype HSA”
