Resumen del Recurso

Pregunta 1

Pregunta
What proteins are found in a sarcomere?
Respuesta
  • Only Actin and Myosin
  • Actin, Myosin, Troponin and Tropomyosin
  • The Myofibril
  • The Sarcoplasmic Reticulum

Pregunta 2

Pregunta
Myofibrils have light and dark bands called neuromuscular junctions.
Respuesta
  • True
  • False

Pregunta 3

Pregunta
The contractile elements of muscle fibres are called ________.
Respuesta
  • Sarcoplasm
  • Myofibrils
  • The Sarcoplasmic Reticulum
  • Fasciculi

Pregunta 4

Pregunta
The sliding filament theory of muscle contraction involves;
Respuesta
  • 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

Pregunta 5

Pregunta
The junction between a nerve and a muscle is called a_____________.
Respuesta
  • Neuromuscular junction
  • Synapse
  • Sarcomere
  • Neurotransmitter

Pregunta 6

Pregunta
A muscle contraction begins with release of _______, which reaches a sarcolemma, depolarizing the sarcolemma.
Respuesta
  • Calcium
  • ATP
  • Troponin
  • Acetylcholine
