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

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
