The rate of osmosis across a cell membrane depends upon which of the following? I: Intracellular solute concentration II: Extracellular solute concentration III: Polarity of solutes IV: Molecular weight of solutes V: The presence of aquaporins

aquaporins

Explanation:

aquaporins are channel proteins that allow water to flow through a membrane. The rate of osmosis depends on ratio of intracellular to extracellular concentration as well as the presence of aquaporins in the cell membrane

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
