NEET 2023, Biology Q3: Structure and Functions of Cell Organelles

NEET2023Biology
Q.

Movement and accumulation of ions across a membrane against their concentration gradient can be explained by:

  1. A

    Osmosis

  2. B

    Facilitated Diffusion

  3. C

    Passive Transport

  4. D

    Active Transport

Solution

Movement against a concentration gradient requires energy input, which only active transport provides. ATP-driven pumps drive the solute uphill from low to high concentration. The other three processes are passive and move solutes only down their gradients.
