Question 1 of 6

1

What proteins are found in a sarcomere?

Select one of the following:

Only Actin and Myosin
Actin, Myosin, Troponin and Tropomyosin
The Myofibril
The Sarcoplasmic Reticulum

Explanation

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

1

The contractile elements of muscle fibres are called ________.

Select one of the following:

Sarcoplasm
Myofibrils
The Sarcoplasmic Reticulum
Fasciculi

Explanation

Question 4 of 6

1

The sliding filament theory of muscle contraction involves;

Select one of the following:

Calcium ions releasing ATP for energy
Calcium ions binding with troponin, which shifts tropomyosin and allows the myosin-binding sites on actin to be exposed
Neuromuscular junctions directly producing the movement of actin and myosin
Actin filaments moving the myosin filaments in each sarcomere

Explanation

Question 5 of 6

1

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

Select one of the following:

Neuromuscular junction
Synapse
Sarcomere
Neurotransmitter

Explanation

Question 6 of 6

1

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

Select one of the following:

Calcium
ATP
Troponin
Acetylcholine
