Vedclass · Answer

(A) During muscle contraction,$ATP$ is essential for the detachment of the myosin head from the actin filament. $1$. When an $ATP$ molecule binds to the myosin head,it causes the cross-bridge to detach from the actin filament. $2$. Subsequently,the hydrolysis of $ATP$ into $ADP$ and inorganic phosphate $(Pi)$ provides the energy required to 'cock' the myosin head into its high-energy position. $3$. This energized myosin head then forms a new cross-bridge with the actin filament,leading to the power stroke that causes muscle contraction. Therefore,the energy provided by $ATP$ is primarily utilized for the detachment of the cross-bridge and the subsequent preparation for the next cycle.
