BIOXI20: LOCOMOTION AND MOVEMENT

340060 Assertion :
The sarcoplasmic reticulum releases \(\mathrm{Ca}^{++}\)in the sarcoplasm on receiving action potential via \(\mathrm{T}\) - tubules.
Reason :
Active site of actin myofilament is uncovered by \(\mathrm{Ca}^{++}\)which allows meromysin head to join this site.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.

1 Red fibres; white fibres
2 White fibres; red fibres
3 White fibres; yellow fibres
4 Red fibres, yellow fibres
BIOXI20: LOCOMOTION AND MOVEMENT

340062 Assertion :
A person undergoes fatigue very soon during exercise.
