Muscle contraction process. which statement is true? neurotransmitter binds to thin filament? t tubules help transmit the action potential deep into the muscles of the cell stimulating the release of calcium? muscle cells can contract without the presence of calcium?
Added by Daniel O.
Step 1
Here, the neurotransmitter acetylcholine is released and binds to receptors on the muscle cell membrane. This triggers the opening of ion channels, allowing sodium ions to enter the muscle cell and depolarize it. Show more…

'Which of the following is a correct statement about skeletal muscle contraction? At high [Ca2+], the myosin binding sites on actin are blocked by tropomyosin All of the above are true_ An increase in intracellular Ca2+ pushes tropomyosin away from the thick filament; resulting in contraction Contraction is a result of myosin filaments sliding into actin filaments:'
