Suppose molecules were unable to diffuse into and out of the cells. How might life be different if cells had to use active trans
antiseptic1488 [7]

Answer:

Cells would most probably not exist because these units of life metabolize energy molecules like glucose to harness their energy for the running of biochemical processes, like active transport, to support life. However, harnessing this energy from these energy molecules is NOT 100 percent efficient. A higher percentage of energy is lost as heat in the process.

Therefore if the cells were required to carry all molecules in and out of the cell, actively, including the energy molecules themselves (which is counterintuitive), this would require a lot of energy and would be unsustainable. This would be analogical to the counteracting and infinite loop of more fuel needed to carry the mass of the more fuel in space travel...
