Why is diffusion and osmosis important to the cell

Uses energy to move substances against (up) a concentration gradient or across a partially permeable membrane. In active transport a special transport protein in the cell membrane picks up the useful particle on one side of the membrane. The transport protein then rotates through the membrane and releases the particle on the other side of the membrane. This uses energy from cellular respiration.

Processes above and be sure to mention the movement of electrons and energy as the carbon atom moves from one reaction to another.
