Question

How many ATP molecules are used for facilitated diffusion?

Answer 1

Role of ATP molecules in facilitated diffusion:

1. The ATP molecule breaks down to release energy with Adenosine diphosphate ADP and inorganic phosphate as co-products.
2. Facilitated Diffusion is a diffusion mechanism of solutes from higher concentration to lower concentration.
3. The process takes place naturally and is guided by the protein molecules called integral membrane proteins, which form the pore or channel.
4. Thus, as the transfer takes place down the concentration gradient, it does not require the presence of ATP, to carry out facilitated diffusion.
