Question

quiz information question 8 (1 point) which of the following does not happen during rigor mortis? myosin head stuck in a cross - bridge calcium ions leak out of sr run out of atp acetylcholinesterase inhibitor is released what part of the muscle fiber functions to restore sarcomere length after a contraction and resist extreme stretching of the muscle fiber? titin nebulin z - line m - line

Explanation:

Titin is a large protein that provides elasticity and helps restore sarcomere length and resist over - stretching. During rigor mortis, myosin heads get stuck in cross - bridges, calcium ions leak out of the sarcoplasmic reticulum (SR), and ATP is depleted. Acetylcholinesterase inhibitors are not related to the events of rigor mortis.

Answer:

For the first question "What part of the muscle fiber functions to restore sarcomere length after a contraction and resist extreme stretching of the muscle fiber?": titin
For the second question "Which of the following DOES NOT happen during rigor mortis?": acetylcholinesterase inhibitor is released
