Which ion binds with troponin during muscle contraction?

View answer and explanation

Correct option: B

C{a^{2 + }}

Option B (

C{a^{2 +}}

) is correct because calcium ions bind to troponin, initiating the muscle contraction process.

15 Easy

C{a^2}^ +

and

M{g^{2 + }}

Option D (

C{a^2}^ +

and

M{g^{2 + }}

) is the closest correct answer, although magnesium's role is less direct than calcium's. Calcium is essential for muscle contraction, and magnesium is involved in energy production (ATP) required for muscle function.

Choose wrong statement

View answer and explanation

Correct option: D

Scapula is ramboid bone situated in ventral part of thorax

Option D (Scapula is ramboid bone situated in ventral part of thorax) is correct because the scapula is located on the dorsal, not ventral, part of the thorax and is triangular, not rhomboid.
