Transport of $\mathrm{D}$ - and $\mathrm{L}$-glucose proceeds at the same rate down an electrochemical gradient by which of the following processes?

Question

Quizplus · Accepted Answer

[II A 1, C 1]. Only two types of transport occur "downhill" - simple and facilitated diffusion. If there is no stereospecificity for the $\mathrm{D}$ - or $\mathrm{L}$-isomer, one can conclude that the transport is not carrier mediated and, therefore, must be simple diffusion.
