EKG STUDY MATERIAL FOR ADVENTHEALTH Exam Questions With Verified Answers 3 pacemakers of the heart - answer1. SA node 2. AV node 3. bundle branch intrinsic rate of SA node - answer60-100 bpm intrinsic rate of AV node - answer40-60 bpm intrinsic rate of bundle branches - answer20-40 bpm electrical pathway through the heart - answer1. normal conduction impulse originates in the *SA Node* 2. impulse travels to *AV Node* causing atrial depolarization (contraction) 3. AV Node slightly del...

Buffer Order and Henderson Hasselbach - Water, Buffer, Salt, Base pH = pKa + log(A/HA) pKa decrease as temp increase so pH decrease Ramachandran plots - Φ = N-R ψ = C-R optimal angle to prevent steric hinderance Protein structure of a helix, B sheet, reverse turn - a: LEMARKHQ B: VICYFTW RT: PSDNG how many amino acids in alpha turn helix - 3.6 Super secondary structure - helix turn helix parallel vs. antiparallel - parallel wedges face same way antiparallel face opposite ...

pKa (chapter 3) - measure of the tendency of a group to give up a proton (acidity); tendency decreases tenfold as pKa increases by one unit thioester bond (1) - compounds with functional group C-S-CoA-C (eg, in acetyl-CoA) zwitterion (3) - dipolar ion with both positive and negative groups but overall neutral charge; can act as either an acid or base Isoelectric point (pI) (chapter 3) - the characteristic pH at which the net electric charge is zero SDS - Sodium Dodecyl Sulfate (chap ...

· Turbidity Measurements - Spectrophotometer sends light through a culture. Light absorbance can give a rough measure of cell density in the tube ·Agrobacterium - Crown-Gall Disease - The crown gall is where the stem of the plant connects with the roots of the plant. Causes tumours, parasitism. THIS IS BAD, we don't want this one. Agrobacterium is the only one that can use opine as a carbon and nitrogen source. It robs the plant of organic carbon. We can use agrobacterium to introduce ne...

Henderson-Hasselbach Equation - pH = pKa + log ([A-] / [HA]) 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. Salting Out (Purification) - Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. Size-Exclusion Chromatography - Separates sample based on size with smaller molecules eluting later. Ion-Exchange...

Decrease in ICP c. Involvement of vestibular nuclei d. Decompression of brainstem - correct answer C Which criterion is not used when determining brain death? a. Unresponsive coma b. No spontaneous respiration c. Isoelectric electroencephalogram (EEG) d. Ocular response to head turning - cor...

BCH403 FINAL EXAM QUESTIONS WITH REVISED ANSWERS – UPDATED!! Which of the following is NOT a potential function of specific transcription factors? - Answer-Melt promoter DNA The following peptide is dissolved in a solution of pH 7. M-D-L-P-S-K. What is the peptide's net charge and can this peptide be purified by ion exchange chromatography? - Answer-0, and it cannot because it is at the isoelectric point. The process by which hydrophobic molecules are driven together, therefore maximiz...
