Verified step by step guidance

Understand the main function of muscles: Muscles convert chemical energy, primarily from ATP, into mechanical energy, which is used for movement.

Identify the property of muscles that allows them to perform this conversion: Contractility is the ability of muscle fibers to shorten and generate force, directly relating to the conversion of chemical energy to mechanical energy.

Differentiate between the properties of muscles: Extensibility refers to the ability of muscles to be stretched, Elasticity is the ability to return to original shape after stretching, and Excitability is the ability to respond to stimuli.

Focus on Contractility: This property is crucial for muscle function as it involves the active process of muscle fibers contracting, which is essential for movement and force generation.

Conclude that Contractility is the property most directly related to the muscle's function of converting chemical energy to mechanical energy, as it involves the active shortening and force generation of muscle fibers.
