WebThe transepithelial flux of puerarin was investigated in both transport directions (A→B and B→A) to determine whether its transport was polarized. The Papp (A→B) of puerarin was between 1.272×10 −6 and 1.313×10 −6 cm/s. The Papp (B→A) of puerarin was between 1.351×10 −6 and 1.411×10 −6 cm/s. Web15 Nov 2024 · The carriers (as in the active transport) are proteins embedded in the cell membrane. The facilitated diffusion is faster than simple diffusion, but as the concentration of the transported substance increases, the carrier is saturated and the rate of facilitated diffusion stops increasing. The ions or molecules are transported with the carrier.

WebThe simplest forms of transport across a membrane are passive.
