Isoelectric point - Study guides, Class notes & Summaries

Electrocardiogram (ECG) - Since you can't see the heart beating we use a ECG to provide a picture that replicates the actual cardiac issue. Myocardial Infraction (MI) - Heart Attack -Have abnormal rhythms. -Death of cardiac muscle due to ischemia Doe the ECG machine monitor or control the hearts rhythm? - Only monitors Straight line when machine is turned on but not connected to the patient - Isoelectric = no current It is straight because there is a balanced electrical force field. Thi...

(*Molecular Biology) Hydrolases correct answers Enzymes that catalyze reactions between a specific substrate and water in order to break a covalent bond. (*Molecular Biology) pI (Isoelectric point) of an amino acid correct answers The pH at which an amino acid carries no electrical charge (average of the pKa's of the carboxyl and amino group) (*Genetics) Silent Mutations correct answers Mutations that do not change the amino acid sequence (*Molecular Biology) When are Amino aci...

· 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...

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 ...

ACS Biochemistry Final Exam Questions and Correct Solutions 2024 pKa (chapter 3) - Answer -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) - Answer -compounds with functional group C-S-CoA-C (eg, in acetyl-CoA) zwitterion (3) - Answer -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) - Answer -the ch...

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...
