Document Summary
Multiple choice questions (1 mark per answer: the thick filaments of skeletal muscle cells are composed of the protein, keratin, actin, kinesin, myosin, titin, what properties of intermediate filament monomers distinguish them from the monomers that. Which of the conclusions below can she draw: vesicle movement is driven by a motor protein that hydrolyzes atp, vesicle movement relies on the presence of microfilaments, vesicle movement occurs by the action of kinesin, vesicle movement relies on the presence of microtubules, none of a, b, c, or d is a valid conclusion given her observations, skeletal muscle contraction relies on, the availability of atp and ca2+ ions, the rapid polymerization of actin monomers into microfilaments coupled with the action of myosin motor proteins, the sliding of microtubules over each other, driven by the motor protein dynein, the activity of the motor protein myosin ii within a stabilized array of microfilaments, both a and d are true of skeletal muscle contraction.
