Please explain.
Which of the following is incorrect about the function of structures found within a muscle fiber? O As action potentials propagate deep into muscle fibers along T-tubules, they cause a conformational change in the DHPR. The neurotransmitter released by a motor neuron onto the motor endplate at the neuromuscular junction is acetylcholine (ACh). O O According to the sliding filament hypothesis, during muscle contraction, the I Band, H zone, and sarcomere all "shink" while the A band does not. During relaxation, titin and other structural proteins (including those found in connective tissue) enable the sarcomeres to return to their resting lengths O O Rigor is characterized by the tight binding of myosin to actin in the presence of ATPExplanation / Answer
during relaxation titin and other structural proteins (including those found in connective tissue) enable the sarcomeres to return to their resting lengths will be the answer because
The contraction of a striated muscle fiber occurs as the sarcomeres, linearly arranged within myofibrils, shorten as myosin heads pull on the actin filaments. The region where thick and thin filaments overlap has a dense appearance, as there is little space between the filaments.
