Question

The mechanism of passive or facilitated diffusion require
A.metabolic energy
B. concentration of solute against an electrochemical gradient
C. accumulation of solute against an electrochemical gradient
D. accumulation or concentration of solute against an electrochemical gradient

$\textbf{Hey there!}$

=>Here is ur Answer<=

The answer is $\textbf{A}$. Both types of transport occur down an electrochemical gradient and do not require metabolic energy. Saturability and inhibition by
other sugars are characteristic only of carrier-mediated glucose transport. thus, facilitated
diffusion is saturable and inhibited by galactose whereas simple diffusion is not.
