- Can this be considered positive or negative mechanism?arrow_forwardWhat does it mean to say a graded potentialcan summate and then spread in a decrementalfashion?arrow_forwardIn many organisms, the central nervous system relies on specialized cells called neurons to propagate an electrochemical signal along the axon of each neuron. The propagation of this signal relies on the sodium-potassium pump, a membrane-bound protein that alter- natingly moves three sodium ions outside of the cell against the concentration gradient and moves two potassium ions into the cell along the concentration gradient. Based on the information above, which is most likely true about the sodium-potassium pump? A B с D It requires ATP to move the sodium ions outside of the cell and to move potassium ions into the cell. It requires ATP to move the potassium ions into the cell. It requires ATP to move the sodium ions outside of the cell against the concentration gradient. It does not require ATP to move the sodium ions outside of the cell or to move potas- sium ions into the cell.arrow_forward
