- What is the difference between the vibratory movement of the translation movement?A healthy 32-year-old man lifts weights regularly as part of his workout. In one of his biceps muscle fibers at rest, the length of the I band is 1.0 μm and the A band is 1.5 μm. Contraction of that muscle fiber results in a 10% shortening of the length of the sarcomere. What is the length of the A band after the shortening produced by muscle contraction? Draw the sarcomere before and after contraction.Why do reticular fibers appear as dark strands on a reticulum-stained slide
- What is meant by the term "Critical concentration" with respect to actin filaments?What is Cross-Bridge Activation?Neurofilament proteins assemble into long, intermediate filaments , found in abundance running along the length of nerve cell axons. The C-terminal region of these proteins is an unstructured polypeptide, hundreds of amino acids long and heavily modified by the addition of phosphate groups. The term “polymer brush” has been applied to this part of the neurofilament. can you suggest why?
