Question
Chapter 7, Problem 15E
Summary Introduction
To explain: The observation that the force generated by the muscle fibers increases as the sarcomere shortens but decreases at very short sarcomere lengths.
Concept introduction: The striated muscles consist of repeated sarcomeres. The sarcomeres are the functional units of the striated muscle. The sarcomeres are arranged from end-to-end to form the muscle fibers.

- Specific rotation is a measure of a solution's capacity to rotate circularly polarized light. The unfolding of the a helix of a polypeptide to a random conformation is accompanied by a large decrease in specific rotation. Polyglutamate, a polypeptide made up of only 1-Glu residues, has the a helix conformation at pH 3. When researchers raise the pH to 7, there is a large decrease in the specific rotation of the solution. Similarly, polylysine (1.-Lys residues) is an a helix at pH 10, but when researchers lower the pH to 7 the specific rotation also decreases, as shown in the graph. a Helix Specific rotation Poly(Glu) a Helix Random conformation Poly(Lys) Random conformation T + ° 2 4 6 В 10 12 14 PH Complete the statements about the molecular mechanism for these changes in specific rotation.

- A protein has a molecular mass of 400 kDa when measured by size-exclusion chromatography. When subjected to gel electrophoresis in the presence of sodium dodecyl sulfate (SDS), the protein gives three bands with molecular masses of 180, 160, and 60 kDa. When electrophoresis is carried out in the presence of SDS and dithiothreitol (DTT), three bands again form, this time with molecular masses of 160, 90, and 60 kDa. How many subunits does the protein have, and what is the molecular mass of each? four subunits: 180, 160, 90, and 60 kDa three subunits: 180, 160, and 60 kDa three subunits: 160, 90, and 60 kDa four subunits: 160, 90, 90, and 60 kDa Correct Answerarrow_forwardCalculate KM and Vmax from the following data: KM= i Vmax [S] (μM) vo (mM.s-¹) 0.1 0.34 0.2 0.53 0.4 0.74 0.8 0.91 1.6 1.04 μM mM s-1arrow_forwardPropose a detailed chemical mechanism for the enzyme catalyzed reaction below and briefly note similarities, if any, to enzymes that we've studied.
