| The advantage of the facilitated diffusion mechanism is that it effectively amplifies the signal from the Dorsal proteins. |
|
| Amino acids and di-peptides cross the cell membrane by active transport and facilitated diffusion, which are mechanisms that require metabolic energy. |
|
| Some are pores that allow molecules of certain types to flow across the membrane at a controlled rate through a process called facilitated diffusion. |
|
| The human placenta, characterized by the processes of passive transport and facilitated diffusion, contains numerous active transport proteins. |
|
| Transport systems that use carrier molecules but which do not require energy to proceed are called facilitated diffusion. |
|
| Diffusion and facilitated diffusion are two examples of passive transport. Passive transport is transport through a cell membrane that does not require energy. |
|
| The four types of chemical transport systems through cell membranes are diffusion, facilitated diffusion, active transport, and pinocytosis. |
|
| We propose a novel mechanism in human airway epithelia that generates a transepithelial glucose concentration gradient by expressing 2 distinct facilitated diffusion transporters in polarized localizations. |
