Definitions:

Myofibrils

Essential components of muscle fibers involved in contraction, made up of a series of repeating units called sarcomeres that give muscles their striated appearance.

Ca2+ Binding

The process by which calcium ions (Ca2+) bind to specific molecules or cellular components, playing crucial roles in various biological processes including muscle contraction and neurotransmitter release.

Cross-bridging

refers to the interaction between actin and myosin filaments in muscle fibers during contraction, allowing for force generation.

Myosin Kinase

An enzyme that phosphorylates myosin light chains, which is crucial in the contraction of muscle cells.
