Detailed explanation-1: -If aquaporins are injected into the membranes of epithelial cells that line blood vessels, a. carrier proteins will bind glucose and enter the bloodstream.
Detailed explanation-2: -Aquaporins are found in a high concentration in the epithelial cells that produce aqueous humor (as well as other epithelial cells that allow water to move readily across their membrane, e.g., epithelial cells in the kidney). These pores allow water molecules through in a single file.
Detailed explanation-3: -Aquaporins are water-permeable membrane-channel proteins found in biological cell membranes that selectively exclude ions and large molecules and have high water permeability, which makes them promising candidates for water desalination systems.
Detailed explanation-4: -At the whole organ level aquaporins modify water conductance and gradients at key “gatekeeper” cell layers that impact on whole plant water flow and plant water potential. In this way they may act in concert with stomatal regulation to determine the degree of isohydry/anisohydry.
Detailed explanation-5: -Aquaporins are channel proteins that facilitate the transport of water across the cell membrane. One group of researchers hypothesizes that without functional aquaporins, no water will be able to enter the cell.
