Naturally, molecules move from an area of high concentration to low concentration without the need of energy. This type of movement is passive transport. Molecules with strong electrical charges such as ions cannot simply diffuse across the cell membrane. Irrespective of their size, their charge prevents them from moving freely across the cell membrane.
In active transport transport proteins pick up molecules and carry them. Passive transport is the movement of materials through a cell membrane without the use of energy.Examples of this are diffusion and osmosis which move form low to high concentration.he movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is k â¦ nown as active transport. Active transport requires energy.
