In carrying out normal activities cells use oxygen and produce carbon dioxide The concentration of oxygen is higher in the blood than inside the cell so oxygen moves into the cell Similarly carbon dioxide moves out of the cell into the blood because the concentration of carbon dioxide inside the cell is greater than the concentration outside the cell How do the small molecules of oxygen and carbon dioxide move through the cell membrane O A active transport by carrier proteins OB passive transport by diffusion OC passive transport by osmosis OD active transport by endocytosis
