Muscle Contraction Quiz

The thick band (w/heads) that is shown with arrow is....

• Actin

• Myosin

• Troponin

• Acetylcholine

The thin band includes all of the following EXCEPT:

• Troponin

• Tropomyosin

• Myosin

• Actin

The energy molecule also needed for muscle contraction to occur is:

• ADP

• ADT

• Ca+

• ATP

This ion diffuses in the cytoplasm between myosin and actin causing them to slide into each other:

• Acetylcholine

• Calcium

• ADP + P

• ATP

This neurotransmitter is released in synapses to trigger muscle contraction:

• Troponin

• Myosin

• Acetylcholine

• Acetylcholinesterase

This enzyme prevents acetylcholine dispersal and activation, therefore, preventing muscle contraction

• Calcium

• Tropomyosin

• Actin

• Acetylcholinesterase

This "line" gets shorter during sarcomere contraction:

• A

• I

• Z

• H

Which proteins are present on thin filaments of muscle cells and assist in muscle contraction (may choose more than one answer)

• Calcium

• Troponin

• Tropomyosin

• Myosin
