Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is more true to cause muscle contraction?
A
Actin Pulls on the myosin
B
Myosin Pulls on the Titin
C
Myosin Pulls on Actin
D
Actin Pulls on Titin
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘A-Band remains constant’.

Detailed explanation-2: -ATP and Muscle Contraction The motion of muscle shortening occurs as myosin heads bind to actin and pull the actin inwards. This action requires energy, which is provided by ATP. Myosin binds to actin at a binding site on the globular actin protein.

Detailed explanation-3: -In summary, myosin is a motor protein most notably involved in muscle contraction. Actin is a spherical protein that forms filaments, which are involved in muscle contraction and other important cellular processes.
