Could be B or C, not enough information is given • Chloride (Cl-) is an ion that is essential for neuronal signaling and regulating action potential/excitability in neurons. When chloride receptors are opened with a neurotransmitter, Cl- flows from high concentration in the synapse (outside of the cell) to low concentration in the neuron cell. ● ● Oxygen gas must cross from the bloodstream into cells and it has the chemical structure O=O. Glucose is a polar molecule that moves from the small intestine, where it is found in high concentration, to inside the cells that line the digestive tract, where it is found in low concentration. Glucose moves into the cell with the help of a protein that changes shape.
