MCQ

During muscle contraction, $ATP$ provides energy for

A
Cross bridge detachment
B
Building up action potential
C
Releasing from sarcoplasmic reticulum
✓
Cross-bridge attachment of myosin to actin

✓

Answer

Correct option: D.

Cross-bridge attachment of myosin to actin

d
Cross-bridge attachment. When $ATP$ binds to myosin filament there is a detachment of myosin and actin filament. Due to detachment, the sliding (contraction) takes place and the hydrolysis of $ATP$ to $ADP$ takes place. In that step again, the cross bridge formation between actin and myosin takes place
