Sliding Filament Quiz

Question 1 of 6 Question 1 of 6

1

What proteins are found in a sarcomere?

Select one of the following:

  • Actin, Myosin, Troponin and Tropomyosin

  • The Sarcoplasmic Reticulum

  • The Myofibril

  • Only Actin and Myosin

Explanation

Question 2 of 6 Question 2 of 6

1

Myofibrils have light and dark bands called neuromuscular junctions.

Select one of the following:

  • True
  • False

Explanation

Question 3 of 6 Question 3 of 6

1

The contractile elements of muscle fibres are called ________.

Select one of the following:

  • The Sarcoplasmic Reticulum

  • Sarcoplasm

  • Fasciculi

  • Myofibrils

Explanation

Question 4 of 6 Question 4 of 6

1

The sliding filament theory of muscle contraction involves;

Select one of the following:

  • Calcium ions releasing ATP for energy

  • Neuromuscular junctions directly producing the movement of actin and myosin

  • Actin filaments moving the myosin filaments in each sarcomere

  • Calcium ions binding with troponin, which shifts tropomyosin and allows the myosin-binding sites on actin to be exposed

Explanation

Question 5 of 6 Question 5 of 6

1

The junction between a nerve and a muscle is called a_____________.

Select one of the following:

  • Neuromuscular junction

  • Neurotransmitter

  • Synapse

  • Sarcomere

Explanation

Question 6 of 6 Question 6 of 6

1

A muscle contraction begins with release of _______, which reaches a sarcolemma, depolarizing the sarcolemma.

Select one of the following:

  • ATP

  • Acetylcholine

  • Troponin

  • Calcium
