| Osmosis and diffusion is called passive transport because it takes no energy to move from a high concentration to a low concentration. |
|
| This clearance was mediated by both active and passive transport processes. |
|
| In this plate we explore three methods for the passive transport of molecules through the plasma membrane. |
|
| Membranes control the composition of cells by active and passive transport. |
|
| The human placenta, characterized by the processes of passive transport and facilitated diffusion, contains numerous active transport proteins. |
|
| The ability to predict and interpret membrane permeation coefficients is of critical importance, particularly because passive transport is crucial for the effective delivery of many pharmaceutical agents. |
|
| Diffusion is considered to be passive transport because no external energy is used. |
|
| This approach allows us to design drug molecules with optimal passive transport properties. |
|
| Diffusion is a passive transport process driven by the concentration gradient at the G L interface. |
|
| To evaluate the importance of passive transport due to currents, an experimental flume study was designed. |
|
| The filtrate inside proximal tubules, however, can be re-absorbed into blood circulation via active or passive transport. |
|
| Unassisted movement is due to diffusion and is called passive transport. |
|
| Diffusion and facilitated diffusion are two examples of passive transport. Passive transport is transport through a cell membrane that does not require energy. |
|
| It optimises the use of vehicles, the assignment of parking spaces and the provision of passive transport auxiliaries such as containers, swap bodies, trailers and wagons. |
|
| Aerobiology is the scientific discipline focusing on the study of the passive transport of organisms and particles of biological origin in the atmosphere. |
|
| These flagella allow zoospores to swim to a favourable environment, whereas monospores and aplanospores have to rely on passive transport by water currents. |
|
| Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane. |
