41. This failure of active transport prevents the glucose and galactose from being absorbed and providing nourishment to the body. 42. Reid's work in the early 1900s on active transport across biological membranes was not fully appreciated until the 1950s. 43. Lipophilicity, protein binding, and active transport mechanisms all influence the absorption and distribution of such chemicals in maternal tissues. 44. Phenanthriplatin is thought to penetrate cell membranes in its ionised form by either passive diffusion or carrier-mediated active transport . 45. From the intestinal epithelial cells, sodium is pumped by active transport via the basolateral cell membrane into the extracellular space. 46. This may occur in addition to or instead of the secondary active transport mechanism established for ACR3 members noted above. 47. Active transport enables these cells to take up salts from this dilute solution against the direction of the concentration gradient.48. Cells lining the tubule have numerous mitochondria to produce enough energy ( ATP ) for active transport to take place. 49. Rosenberg ( 1948 ) formulated the concept of active transport based on energetic considerations, but later it would be redefined. 50. A cavity forms inside the morula, by the active transport of sodium ions from trophoblast cells and osmosis of water.
