Cell membranes contain channels that allow K + ions to leak out consider channel that has diameter of nm and length of nm if channel has resistance of G Ω what is resistivity rho of solution in channel?

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
