The concentration of molecule R in both cell X and cell Y is 7 a.u. Which of the following statements about the net movement of ONLY molecules Q and R between cells X and Y could be correct?
1. Molecules of Q move by facilitated diffusion from cell X.
2. Molecules of Q move by active transport into cell Y.
