If the "free" water molecule concentration outside of a cell is higher than that inside the cell, the solution outside of the cell is

... termed "hypotonic," meaning less solids (or more diluted) than inside the cell. For fluid movement in/out of cells, water will diffuse (via osmosis) from the hypotonic solution to the hypertonic one, assuming a permeable barrier (i.e. cell membrane) allows it. With this case, water will flow into the cell from outside.

Ithink the answer is true

The first means of speeding up reactions mentioned by the speaker is raising the enzymes
