Consider the diagram given below.

Parts labelled as A, B, C, D, E and F respectively indicate.

(1) Sacrum, ilium, pubis, femur, tibia and fibula

(2) Ilium, pubis, sacrum, femur, fibula and tibia

(3) Sacrum, pubis, ilium, femur, tibia and fibula

(4) Ilium, sacrum, pubis, femur, tibia and fibula

In old age, stiffness of joints is due to the 

(1) hardening of bones

(2) inefficiency of muscles

(3) decrease in synovial fluid

(4) enlargement of bones

Oxygen content reduction makes the glycolyse (glycogenesis) intensity increased due to

(1) increase of ADP concentration in cell

(2) increase of ${\mathrm{NAD}}^{+}$ concentration in cell

(3) increase of ATP concentration in cell

(4) increase of concentration of peroxides and free radicals 

Pick out the correct match

(1) Sternum       - 14

(2) Pelvis           - 3

(3) Ribs             - 20

(4) Face            - 5

Match Column-I with Column-II:

(1) A - I, B - II, C - III, D - IV

(2) A - I, B - III, C - II, D - IV

(3) A - I, B - IV, C - III, D - II

(4) A - III, B - IV, C - II, D - I

Sarcomere is the area between:

(1) 2 H-zones       

(2) 2 Z-lines                  

(3) 2 M-lines                  

(4) 2 A-bands

Light bands (thin filaments) contain actin and are called:

(1) A-bands or Isotropic band            

(2) A-bands or Anisotropic bands

(3) I-bands or Isotropic bands           

(4) I-bands or Anisotropic bands

Dark bands (thick filaments) contain myosin and are called:

(1) A-bands or Isotropic band            

(2) A-bands or Anisotropic bands

(3) I-bands or Isotropic bands           

(4) I-bands or Anisotropic bands

Choose the letter from the figure that most appropriately corresponds to the structure:

I.A-band       II. I-band           III.    Sarcomere         IV.     H-zone

V.Myosin       VI.Actin, Troponin, Tropomyosin             VII.   Z –line

(1) I - E, II - D, III - F, IV - G, V - B, VI- C, VII - A

(2) I - E, II - D, III - C, IV - G, V - B, VI - A, VII - F

(3) I - E, II - D, III - F, IV - G, V - C, VI - A, VII - B

(4) I - E, II - D, III - F, IV - A, V - B, VI - C, VII - G

The functions of tropomyosin in skeletal muscle include:
(1) Sliding on actin to produce shortening

(2) Release Ca+2 after initiation of contraction

(3) Acting as "relaxing protein" at rest by covering up the sites where myosin binds to actin

(4) Generates ATP
