What is the difference between passive diffusion and facilitated diffusion?
Facilitated diffusion is different from simple diffusion because O molecules are small. Owater is transported. energy is used. there is no concentration gradient. proteins act as helpers.

Which of the following does not characterize the different factors that affects the rate of diffusion? Mass of molecules diffusing Solute density Temperature Extent of concentration gradient
The protein galactoside permease transports sugars like lactose against a concentration gradient by coupling transport with H* which moves with a concentration gradient. This is an example of Simple diffusion Facilitated diffusion Primary active transport Secondary active transport

What happens to phospholipid mobility when the cell is treated with agents that disrupt the underlying membrane skeleton? options: Their mobility is unchanged. Their mobility is increased because the fences that normally restrict their diffusion are removed. Their mobility is decreased because the fences that normally restrict their diffusion are removed. Their mobility is increased because the treatment raises the temperature.
