Ions that must be present for binding the cross bridges is
1 \(\mathrm{Na}^{+}\)
2 \(\mathrm{Ca}^{2+}\)
3 \(\mathrm{K}^{+}\)
4 \(\mathrm{Mg}^{+}\)
Explanation:
Ions that must be present for binding the cross bridges is calcium ions. - Calcium ions bind the protein complex troponin, exposing the active binding sites on the actin. As soon as the actin binding sites are uncovered, the high-energy myosin head bridges the gap forming a cross-bridge.

The lactic acid generated during muscles contraction is converted to glycogen in:
1 Muscle
2 Kidney
3 Pancreas
4 Liver
Explanation:
Lactic acid generated during muscles contraction this happens because oxygen can't get to the muscles fast enough to keep up with the amount \(f\) energy the muscle needs. When your muscles are making anaerobically, lactic acid is created as a byproduct. - The lactic acid is transported to the liver, when it is converted back into glucose through a process called gluconeogenesis. The glucose can be used for muscles energy or stored as glycogen.

Which of the following is important for muscle contraction and nerve impulse transmission?
1 \(\mathrm{Ca}^{2+}\) ions
2 \(\mathrm{Mg}^{2+}\) ions
3 Both (a) and (b)
4 \(\mathrm{Fe}^{2+}\) ions
Explanation:
Exp. A \(\mathrm{Ca}^{2+}\) ions is important for muscle contraction and nerve impulse transmission. The contraction of the muscle fibers is initiated by the nerve signals that are sent from the CNS through a motor neuron.

The part of sarcomere that both thick and thin filaments are present in
1 'A' band on either side of ' \(\mathrm{H}\) ' zone
2 'I' band on either side of ' \(Z\) ' line
3 Hensen's disc on either side or ' \(M\) ' line
4 The isotropic band
Explanation:
Exp. A The part of sarcomere that contains both thick and thin filaments is present in ' \(\mathrm{A}\) ' band on either side of the ' \(\mathrm{H}\) ' zone.
