Question

process requiring energy for the movement of particles across a cell membrane across against the concentration gradient

Answer 1

Answer:

Active Transport

Explanation:

Answer 2

This process is active transport.

Unlike other methods such as diffusion or osmosis, active transport requires extra energy provided by the organism from such as cellular respiration. In addition, they also require a carrier protein, which can change its shape to bring the substance through the cell membrane.

Some examples requiring active transport may include root hair cells absorbing mineral ions, or our small intestine absorbing digested nutrients into our body.
