Gas Exchange

Why is gas exchange considered a passive process rather than an active one?
Because cells actively pump oxygen and carbon dioxide across membranes using energy.
Because gases move by diffusion along concentration gradients without cellular energy input.
Because gas exchange requires muscular contractions to move gases across surfaces.
