One major adaptation to endurance training is the two-fold increase in mitochondrial volume. Why/how is having a greater mitochondrial volume advantageous in terms of substrate utilization (be specific)? Include in your answer an explanation of the graph below. Include any signal transduction mechanisms for an increase in mitochondrial volume density […]

1. Heparin is a polyanion that inhibits RNA transcription in vitro by binding directly to bacterial RNA polymerase (RNAP). If heparin interferes with the ability of the polymerase to bind DNA in a non-specific fashion, what subunit of RNAP is the heparin binding to? 2. The 5′ end of the […]

An oligomeric protein has a molecular weight of 153000. A 960 mg sample was treated with an excess of 1-fluoro-2,4-dinitrobenzene(sanger’s reagent) until the reaction was complete. Next the peptide bonds were hydrolyzed by heating with concentrated HCl. The product of the complete hydrolysis contained 12 mg of the compound shown […]
