Pаssаge III The cell membrаne is a selectively permeable barrier that regulates the passage оf substances intо and оut of cells. Scientists conducted two experiments to investigate how molecular size and lipid solubility affect the rate at which different molecules cross artificial phospholipid membranes. Experiment 1 Researchers created artificial membrane vesicles and measured the permeability coefficient (P) for various molecules of different molecular weights. The permeability coefficient indicates how readily a molecule crosses the membrane, with higher values indicating faster transport. All molecules tested were uncharged and had similar lipid solubility. Results are shown in Table 1.

Lipid solubility was measured as the partition coefficient (K), which represents the ratio of a molecule's concentration in a lipid phase versus an aqueous phase. Higher K values indicate greater lipid solubility. The time required for 50% of each molecule to cross the membrane was recorded. Results are shown in Figure 1. Screenshot 2025-10-27 084031.jpg According to Figure 1, a molecule with a partition coefficient of 100 would most likely require approximately how much time for 50% membrane crossing?
