Question

Differentiate between the following:

Active transport and diffusion

Answer 1

The difference between Active transport and Diffusion is as follows:-

Serial Number	Active Transport	Diffusion
1	The use of energy to transport nutrients across the cell membrane against a concentration gradient.	The flow of nutrients across the cell membrane without the use of energy. The flow happens through channel proteins in the membrane.
2	Transport occurs from low to high concentration against the concentration gradient.	Transport occurs along a gradient from high to low concentration.
3	In this method, energy(ATP) is required to transport molecules.	In this case, energy is not required to transport molecules.
4	The movement of glucose into or out of a cell is an example of active transport.	Diffusion allows dissolved sodium and potassium ions to flow across the cell membrane.
