Facilitated diffusion

Vedclass · Answer

(B) $1$. Diffusion is a passive process that does not require carrier proteins or energy.$2$. Facilitated diffusion is a type of passive transport where specific carrier proteins are required to move molecules across the membrane,but it does not consume $ATP$ (energy).$3$. Active transport requires both carrier proteins and energy $(ATP)$ to move molecules against the concentration gradient.$4$. Therefore,the process that requires a carrier molecule but does not utilize energy is facilitated diffusion.

In which transport,carrier molecule is necessary but energy is not utilised?
