Which statement about aquaporins is false? a. they use arg and his side chains to remove associated water molecules from the ‘transported’ h2o. b. they use hydrogen bonding to side chain nh2 groups of two asn residues to exclude proton transport within the pore. c.they transport water and hydronium ions efficiently. d. they have a narrow constriction approximately equal to the van der waals diameter of a water molecule.

Correct option - C

They transport water and hydronium ions efficiently

Explanation:

Aquaporins selectively collect the water molecules in and out of the cell.

While preventing the passage of ions and other solutes it competely block the ions including protons and also important to conserve the electrochemical potential difference in the membrane.

Therefore, the following statement is false.

They transport water and hydronium ions efficiently

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
