Which mnemonic relates specifically to the relationship between sodium and potassium across a cellular membrane?

Explanation:
The correct answer, "Salty Banana," effectively represents the relationship between sodium and potassium across a cellular membrane, particularly in the context of the sodium-potassium pump, which is vital for maintaining cellular homeostasis. In this mnemonic, "salty" refers to sodium ions (Na+), which are abundant outside the cell and contribute to the electrochemical gradient. The "banana" symbolizes potassium ions (K+), which are found in higher concentrations inside the cell. This phrase helps recall that sodium is typically higher outside the cell while potassium is greater inside, which is crucial for understanding how the sodium-potassium pump works. The sodium-potassium pump actively transports 3 sodium ions out of the cell and brings 2 potassium ions in, utilizing ATP for energy. This mechanism is essential for functions such as cell volume regulation, electrical excitability in neurons and muscles, and overall cellular metabolism. Thus, this mnemonic succinctly captures both the ions involved and their concentration gradients, serving as a helpful tool for memorizing the key concepts related to cellular transport dynamics.
