Question

State whether the statement is true or false.

ATP is involved in both sliding filament mechanism and in the maintenance of calcium pump.

• A. True
• B. False

Answer 1

The correct option is A True

• The muscle contraction cycle is triggered by calcium ions binding to the protein complex troponin, exposing the active-binding sites on the actin.
  
• ATP then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.

So, the correct option is 'True'.
