The process by which substances can be absorbed against a concentration gradient is called "Active Transport".

Here are the steps involved in this process:

1. The molecule that needs to be transported binds to a specific site on the carrier protein embedded in the cell membrane.

2. On binding, the carrier protein changes its shape. This change in shape could be triggered by the binding of the molecule itself or through the use of energy from ATP.

3. As the protein changes its shape, it releases the molecule on the other side of the membrane.

4. The protein then returns to its original shape, ready to transport another molecule.

This process allows cells to move substances against their concentration gradient, which means from an area of lower concentration to an area of higher concentration. This is different from passive transport (like diffusion or osmosis) where substances move along their concentration gradient (from an area of higher concentration to an area of lower concentration) and no energy is required.
