Question
Matching Muscles Proteins A. Titin B. Myomesir C. Nebulin D. Dystrophin E. None of the Above 9Contractile Proteins o Helps a sarcomere return to its resting length after stretching 11-Maintains alignment of than filaments in the sarcomere 11Form the M line 13 Has spiral-like structure 4Found in the center of H zone 1s Can stretch to four hines its resting length and spring back unharmed 1-Helps transmit the tension germerated by the Sarcomere to the tendons 17-Connect to titin and adjacent thick filament -.Regulatory proteins 9This is an inelastic proteinExplanation / Answer
63. (c) The contraction of a muscle exerts a pull on a bone because the muscles are attached to bones by tendons.
64. (b) The detachment of the myosin cross-bridges is directly triggered by the attachment of ATP to myosin heads.
65. (c) A muscle producing peak tension during rapid cycles of contraction and relaxation is said to be complete tetanus.
66. (d) The smooth, steady increase in muscular tension produced by increasing the number of active motor units is called recruitment.
67. (d) The type of contraction in which tension rises but the resistance does not change is an isometric contraction.
68. (c) Large diameter, densely packed myofibrils, large glycogen reserves and few mitochondria are characteristics of fast fibers.
