• A) 5.52 × 10⁵ N ∙ m²/C
• B) 1.13 × 10⁵ N ∙ m²/C
• C) 2.26 × 10⁵ N ∙ m²/C
• D) zero

Definitions:

Permeable

Capable of allowing fluids or gases to pass through it.

K+

Potassium ion, a key electrolyte in the body involved in nerve function, muscle contraction, and fluid balance.

Leak Ion Channels

Channels in cell membranes that allow ions to pass through without the need for stimulus, balancing cellular ion concentrations and membrane potentials.

Myofilament

Protein filaments, including actin and myosin, that are the fundamental components of muscle contraction.
