Scopes & Assumptions
Mechanism of ATP utilization other than nucleotide metabolism and the Na+/K+ pump (75%) is not specifically defined
Ca2+ transport not included
Guanine nucleotide metabolism neglected
- little information, minor importance
Cl-, HCO3-, LAC, etc. are in “pseudo” equilibrium
No intracellular concentration gradients
Rate constants represent a “typical cell”
Surface area of the membrane is constant
Environment is treated as a sink
