Which statement is true regarding muscle contraction?
Selected
Answer: The thick filament needs ATP to bind to the thin filament.
Answers:
The T-Tubules help transmit the action potential deep into the
muscle cell stimulating the release of calcium.
The thick filament needs ATP to bind to the thin filament.
The axon terminal of the nerve cells comes into direct
contact with the muscle cell.
Muscle cells can contract with the use of calcium.
• Question 6
ATP is needed in muscle contraction for what process?
Selected
Answer: For the cross-bridge to occur
Answers: For the thick filament and thin filament to bind
For calcium to be released into the cytoplasm of
the cell
For the cross-bridge to occur
For the release of the thick filament from the
thin filament
