Options

  1. AIt generates energy for ATP production
  2. BIt stores oxygen
  3. CIt helps in cross bridge formation
  4. DIt regulates the release of calcium ions

Correct answer

B. It stores oxygen

Step-by-step solution

Muscle contraction is initiated by a signal sent by the central nervous system (CNS) via a motor neuron.The junction between a motor neuron and the sarcolemma of the muscle fibre is called the neuromuscular junction or motor-end plate.When a neural signal reaches the neuromuscular junction, it releases a neurotransmitter (Acetylcholine) which generates an action potential in the sarcolemma. Muscle contains a red coloured oxygen-storing pigment called myoglobin. Myoglobin stores oxygen and helps muscles in producing
