What generates the peak at 410 nm? a. The heme group of cytochrome c b. The heme group of bovine serum albumin c. W residues of proteins d. C residues of proteins e. Y residues of proteins

Liposomes used in these vaccines contain some cationic lipids, or lipids with a positively charged head group.  Explain why this is a sensible strategy for delivering genetic materials (or drugs) to a human cell.

Chemistry Red cells have a volume of ~86 fL. If the concentration of hemoglobin in red cells is ~330 g/L and its Mr is 64,500   b) In the generation of a red cell, the synthesis of all the hemoglobin molecules of the cell takes about 40 h. How many hemoglobin molecules are synthesized in one second per red cell? c) How many subunits (monomers) of hemoglobin are produced in one minute?

Indicate which of the following descriptions is true about the biochemical depicted here: NH₂ +41 5 HO- он он OH OH OH a. Ribonucleotide b. Complementary to dTTP c. Purine d. Key reagent in Sanger sequencing e. Answers b., c. and d. are correct

Identify the incorrect statement regarding the polypeptide, Myoglobin. Select one: a. The interaction between Myoglobin and O2 is homotopic in nature as indicated by a Hill coefficient n = : 1 b. Myoglobin is found predominantly in muscle tissue because it facilitates oxygen diffusion. c. The majority of Myoglobin's secondary structure is composed of alpha-helices d. Myoglobin has a higher affinity for oxygen than Hemoglobin e. Myoglobin serves as an oxygen storage protein as suggested by its hyperbolic binding of 02

What is the fractional occupancy of a protein binding site when the ligand concentration (L) =1mM and the ligand equilibrium binding constant at the binding site K10= 10microM. 0.01 B.0.1 C.0.91 D.0.99 none of the listed values

Previously Protein A and 5mM of ligand X were combined in a neutral solution and 36% of Protein A was ligand bound. Now Protein A and ligand X are combined in an acidic solution. You now find that when there’s a 4 mM concentration of free ligand X, 45% of the protein is bound to ligand. How does a change in pH affect protein A’s affinity for ligand X?   a. Protein A has a higher affinity for ligand X in acidic environments b. Protein A has a lower affinity for ligand X in acidic environments c. The solution pH does not affect the affinity of protein A for ligand X. d. The solution pH does not affect the affinity of a protein for a ligand.
