How is active transport different from simple diffusion?Both active transport and simple diffusion transport molecules against the concentrationgradient.In active transport, molecules are moved down the concentration gradient; on theB contrary, molecules to be transported in simple diffusion are moved against theconcentration gradient.In active transport, molecules are transported with the aid of transport proteins; on the© other hand, molecules to be transported in simple diffusion do not need transportproteins.In active transport, molecules that are transported does not need metabolic energy; incontrast, molecules transported in simple diffusion need metabolic energy.

Often molecules are transported between cells via different means. This transportation is essential…
