238266 Creatinine is formed metabolically from

1 Arginine
2 Histidine
3 Tryptophan
4 Phenylalanine
Locomotion and Movement

238269 The striated appearance of a myofibril is due to the distribution pattern of

1 actin and myosin
2 fascicles
3 troponin
4 meromyosin
5 sarcoplasmic reticulum
Locomotion and Movement

238270 Read the statements regarding a myofibril and choose the correct option.
1 - Each myofibril has alternate dark and light bands.
2 - In the centre of each ' \(A\) ' band is an elastic fibre called ' \(Z\) ' line.
3 - 'A' and ' \(I\) ' bands are arranged alternatively throughout the length of the myofibril.
4 - Sarcomere is the functional unit of contraction.
5 - The central part of the thick filament, not overlapped by a thin filament is the ' \(M\) ' line.

1 1, 3 and 5 alone are correct
2 2 and 5 alone are correct
3 2 and 3 alone are correct
4 1, 3 and 4 alone are correct
5 1, 3 and 2 alone are correct
Locomotion and Movement

238268 Choose the wrongly matched pair

1 Portion of myofibril - Sarcomere between two 'Z' lines
2 Isotropic band - Actin
3 Anisotropic band - Myosin
4 Central part of I-band - M-line
5 Central part of A-band - H-zone
