What makes active transport different from diffusion

Answer 4. Answer 5. Answer 6. Answer 7. Answer 8. Answer 9. Question 1. Question Question 2. Question 3. Question 4. Question 5. Figure 2: Active Transport. Diffusion: Diffusion is the passive movement of molecules along a concentration gradient of higher concentration to a lower concentration. Active Transport: Active transport is the movement of particles across a cellular membrane from a lower to a higher concentration by the use of metabolic energy.

Diffusion: Diffusion occurs through a concentration gradient. Active Transport: Active transport occurs against a concentration gradient. Diffusion: Diffusion is a passive process, which does not require metabolic energy in order to transport molecules across the cell membrane. Active Transport: Active transport requires metabolic energy in the form of ATP for the transportation of molecules across the cell membrane.

Diffusion: Water, oxygen, carbon dioxide, small monosaccharides, sex hormones and other small, hydrophobic molecules are transported through the cell membrane by diffusion.

Active Transport: Proteins, ions, complex sugars, and large cells are transported through the cell membrane by active transport. Diffusion: No net movement of molecules is observed after the establishment of equilibrium on either side of the membrane. Active Transport: No equilibrium of molecules is established in active transport. Diffusion: Diffusion maintains a dynamic equilibrium of water, gases, nutrients, and wastes in and out of the cell.

Active Transport: Active transport allows the transportation of molecules like nutrients and wastes against the concentration gradient.

Diffusion: Oxygen moving from the airways and diffusion of molecules from the blood to the cells through the interstitial fluid are examples of diffusion.

Diffusion and active transport are two methods of transporting molecules across the cell membrane. Diffusion is a passive process, but active transport requires metabolic energy or an electrochemical gradient for the transportation of molecules across the membrane. Simple diffusion occurs directly through the cell membrane. Active transport. Substances more from low to higher concentration up a concentration gradient. Mineral ions into plant roots.
