The figure is titled Solution Surrounding Cell and presents the manner in which several different ions and molecules move through a cell membrane. For each ion or molecule, the relative concentration on each side of the membrane is indicated. From left to right, the diagram is labeled as follows. The molecule is labeled “High O subscript 2” on top, and “Low O subscript 2” on bottom. An arrow is shown starting from the top and going downward through the plasma membrane. The ion is labeled “High N a superscript plus” on top, and “Low N a superscript plus” on bottom. An arrow is shown starting from the top and going downward through a channel protein. The molecule is labeled “High Glucose” on top, and “Low Glucose” on bottom. An arrow is shown starting from the top and going downward through a channel protein. The ion is labeled “High N a superscript plus” on top, and “Low N a superscript plus” on bottom. An arrow is shown starting from the bottom and going upward through a channel protein. The ion is labeled “Low K superscript plus” on top, and “High K superscript plus” on bottom. An arrow is shown starting from the top and going downward through the same channel protein as the N a superscript plus is flowing. The manner in which several different ions and molecules move through a cell membrane is shown in the diagram above. For each ion or molecule, the relative concentration on each side of the membrane is indicated. Which of the following accurately describes one of the movements taking place?单项选择题

The image shows a drawing of a cell membrane running horizontally. The area above the cell membrane is labeled Cytosol, and the area below the cell membrane is labeled Extracellular Fluid. On the left side of the membrane, an arrow that passes directly through the membrane connects a large group of white circles in the extracellular fluid to a small group of white circles in the cytosol. In the middle of the membrane, an arrow that passes between two large ovals that span the membrane connects a large group of black rectangles in the extracellular fluid to a small group of black rectangles in the cytosol. On the right side of the membrane, an arrow that passes through a large rectangle that spans the membrane connects a small group of black ovals in the extracellular fluid to a large group of black ovals in the cytosol. Which of the following scientific questions is most relevant to the model represented in the figure above?
