Action potential in sarcolemma of muscles causes the release of which ions from sarcoplasmic reticulum?
1 \(\mathrm{Na}^{+}\)
2 \(\mathrm{K}^{+}\)
3 \(\mathrm{Ca}^{2+}\)
4 \(\mathrm{Fe}^{2+}\)
Explanation:
A neural signal reaching this junction releases a neurotransmitter (Acetyl choline) which generates an action potential in the sarcolemma. This spreads through the muscle fibre and causes the release of calcium ions from sarcoplasmic reticulum into the sarcoplasm.

The reaction which change lactic acid into glycogen come under
1 Calvin cycle
2 Krebs cycle
3 Coricycle
4 Glycolysis
Explanation:
Repeated activation of the muscles can lead to the accumulation of lactic acid due to anaerobic breakdown of glycogen in them, causing fatigue. Fatigue is the inability of the muscle to contract due to deposition of lactic acid by repeated contraction. Lactic acid is transported to liver by blood and converted to glycogen through Cori's cycle.

Sliding filament theory can be best explained as
1 Actin and myosin filaments shorten and slide pass each other
2 When myofilaments slide pass each other actin filaments shorten while myosin filaments do not shorten.
3 Actin and myosin filaments do not shorten but rather slide pass each other
4 When myofilaments slide pass each other myosin filaments shorten while actin filaments do not shorten
Explanation:
Actin slides over myosin.
