Why does our body need to carry out active transport when we can just use diffusion normally? Does it really need to go against the concentration gradient and use up ATP? If so why?

Sorry i tend to ask questions in order to understand a topic even though i dont need to know at my level, Thank you very much )

What substance are you talking about with this active transport. Respiratory gasses are not 'transported' via active transport, so I'm not sure what you're talking about here with the breathing.

Oh sorry that was a mistake um Im just talking about the whole process of active transport, is it really needed when we have diffusion already?

Hey, you do need to know this content for GCSE exams . Active transport goes against the concentration gradient, which means it goes from an area where there are fewer particles to an area with a large number of particles. active transport requires ATP because the carrier proteins (a block of cell with a hole in ) move the particles to the other side of the membrane(the place with a higher number of particles).To do this movement, it needs ATP and this ATP is obtained through respiration. Diffusion is a natural process as particles naturally drift from an area of high concentration to a an area of low concentration to create equilibrium within the particles
Also I am not sure if this is all right because I have just finished my GCSE but if you need any more clarification on the information please feel free to pm me

Gasses in the body do not require Active transport they use diffusion.Active transport,I think, is done in the villi to move glucose I am not sure
