Biological Basis of the Code

The code models the sodium-potassium pump (Na⁺/K⁺-ATPase) in neural membranes, a crucial enzyme that maintains the electrochemical gradients of sodium (Na⁺) and potassium (K⁺) ions across the cell membrane. These gradients are essential for various physiological functions, including nerve impulse transmission and muscle contraction.

Key Biological Features

Sodium (Na⁺) and Potassium (K⁺) Ions

ATP and Phosphorylation

Pump Cycle Components

Temperature and Voltage Dependence

Functionality and Ion Transport

The Na⁺/K⁺-ATPase pump actively transports 3 Na⁺ ions out of the cell and 2 K⁺ ions into the cell against their concentration gradients. This active transport is fueled by ATP hydrolysis, a key biochemical aspect captured in the code. The pump's activity is quantified via the atpact variable, which captures its electrical current contribution in microamperes per square centimeter.

Molecular and Electrical Balance

Overall, this model encapsulates the complex interplay of biochemical and biophysical aspects of the Na⁺/K⁺-ATPase, highlighting its vital role in maintaining the resting membrane potential and the overall homeostasis in neural cells.
