Question

4. Why do we say that diffusion is a passive process ?
5. What will happen, when RBCs are placed in an isotonic solution ?​

Answer 1

Diffusion is a passive process because it does not require ATP.

Explanation:

• Diffusion can be described as a process in which molecules move from a higher concentration to a lower concentration.

• Energy is not required in this process, hence this process is termed as passive process.

• If RBC are places in isotonic solution,no molecules will pass inside or outside.

• This is because in isotonic solution has the same concentration of solutes outside and inside of the cell.
