1. What happens if an animal cell is in contact with a hypotonic solution which has a lower colute concentration than the cell?
2. energizes other molecules in cells by transferring phosphate groups to those molecules
3. during protien production by the cell, secretory proteins exit the cell from transport vesicles that fuse with the plasma membrane spilling the contents outside the cell
