When a signaling molecule binds to the GPCR, the G protein alpha subunit exchanges GDP for GTP. The alpha subunit dissociates from the beta and gamma subunits and interacts with other molecules, ultimately triggering a cellular response. ... GTP is hydrolyzed to GDP, and the signaling molecule comes off of the receptor.
The process of osmosis is the movement of water through a selectively permeable membrane from an area of higher concentration to an area of lower concentration.
If 1% sugar solution is placed in pure water, then there would be a higher concentration of water molecules outside the cell compared to inside the cell. The solution outside the cell would be hypo-tonic (containing fewer solute molecules than inside the cell). Water will move into the cell by inward osmosis and the cell would then swell.
