Text Solution

Verified by Experts

The correct Answer is:
B
The solute can move downhill from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. This process is called facilliated diffusion and it does not require energy. It is highly selective process as it allows the uptake of only specific and selected substances.
It requires special membrane proteins called carrier proteins for the transport of substances.
The solute can move uphill, from regions of lower to higher concentration in a process called active transport, which requires some form of chemical energy.
