1. Henderson-Hasselbach Equation: pH = pKa + log ([A-] / [HA]) 2. FMOC Chemical Synthesis: Used in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the N-terminus. 3. Salting Out (Purification): Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. 4. Size-Exclusion Chromatography: Separates sample based on size with small- er molecules eluting later. 5. Ion-Exc...

ACS Biochemistry First Semester 2023 Exam Questions With Correct Answers Buffer Order and Henderson Hasselbach - ANSWERS Water, Buffer, Salt, Base pH = pKa + log(A/HA) pKa decrease as temp increase so pH decrease Ramachandran plots - ANSWERS Φ = N-R ψ = C-R optimal angle to prevent steric hinderance Protein structure of a helix, B sheet, reverse turn - ANSWERS a: LEMARKHQ B: VICYFTW RT: PSDNG how many amino acids in alpha turn helix - ANSWERS 3.6 ...

ACS Biochemistry Comps EXAM QUESTIONS WITH COMPLETE SOLUTIONS Ion-Exchange Chromatography - ANSWERS Separates sample based on charge. CM attracts +, DEAE attracts -. May have repulsion effect on like charges. Salt or acid used to remove stuck proteins. Hydrophobic/Reverse Phase Chromatography - ANSWERS Beads are coated with a carbon chain. Hydrophobic proteins stick better. Elute with non-H-bonding solvent (acetonitrile). Affinity Chromatography - ANSWERS A...

DAT Biology Practice Test Questions/Concepts Operant conditioning - ANS the use of reinforcement to condition a response to a stimulus (Ex: electric shocks to teach a mouse where to go) Discrimination - ANS the ability of the learning organism to differentially respond to slightly different stimuli Pavlovian conditioning - ANS autonomic response to an environmental stimulus (Ex: dog salivates upon hearing bell because owner feeds him when rings bell everyday) ...
