How do aquaporins allow the passage of H2O but not H3O+?

#Unit 2. Cellular Organization
  1. aquaporin interrupts this process by forming covalent bonds from the side chain NH2 groups of two highly conserved Asn residues to a water molecule that is centrally located in the pore.
  2. aquaporin interrupts this process by forming hydrogen bonds from the side chain NH2 groups of two highly conserved Asp residues to a water molecule that is centrally located in the pore.
  3. aquaporin interrupts this process by forming hydrogen bonds from the side chain NH2 groups of two highly conserved Asn residues to a water molecule that is centrally located in the pore.
  4. aquaporin interrupts this process by forming hydrogen bonds from the side chain COO- groups of two highly conserved Asn residues to a water molecule that is centrally located in the pore.
