Which processes can move solutes against concentration gradi

Which process(es) can move solutes against concentration gradients? (from low to high concentration) Passive Diffusion Facilitated Diffusion Active Transport Secondary Transport Active Transport Active and Secondary Transport Active, Secondary Transport and Facilitated Diffusion All processes

Solution

The correct answer is Active transport.

Rest all the categories are types of diffusion. Diffusion always occurs down or along the concentration gradient, whethrr with or without support of carrier molecule.

Transport which occurs against the concentration gradient, uses ATP and is ACTIVE TRANSPORT.
