The sarcoplasmic reticulum stores and releases calcium ions for muscle contraction.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Muscle Contraction - Sliding Filament Theory and Regulation
Myosin ATPase hydrolyzes ATP, providing energy for the power stroke in muscle contraction.

ATP provides the energy required for the movement of myosin heads during muscle contraction.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Muscle Contraction - Sliding Filament Theory and Regulation
Myosin heads form cross-bridges with actin filaments during muscle contraction.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Muscle Contraction - Sliding Filament Theory and Regulation
Calcium ions are essential for muscle contraction as they help in cross-bridge formation.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Muscle Contraction - Sliding Filament Theory and Regulation
During contraction, actin filaments slide over myosin filaments, not away from them.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Muscle Contraction - Sliding Filament Theory and Regulation
ATP is required for cross-bridge formation and subsequent muscle contraction.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Muscle Contraction - Sliding Filament Theory and Regulation
Myosin heads contain ATPase, which helps in ATP hydrolysis for muscle contraction.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Muscle Contraction - Sliding Filament Theory and Regulation
ATPase, present in myosin heads, hydrolyzes ATP to provide energy for muscle contraction.
