3) Out of the type of transport and diffusion we learned, which type of transport and diffusion is when a solute moves against its concentration gradient?
1) The types of passive transport is simple diffusion.
2) Diffusion is to move solute from high concentration to low concentration as to active transport is to move solute from low concentration to high concentration with the help from ATP.
3) Out of the type of transport and diffusion we learned, active transport is when a solute moves against its concentration gradient.
