Why Does Active Transport Need Energy [upd] -

❌ ✅ Partly true, but incomplete. Energy is primarily used to change the shape of the pump protein, which forces the particle through a "trap door" against its will. Final Takeaway (One Sentence) Active transport needs energy because it performs the unnatural act of moving substances from where they are less abundant to where they are more abundant, fighting against the universal tendency toward equilibrium.

❌ ✅ No. Channel proteins and some carrier proteins (facilitated diffusion) are passive. Only pumps (carrier proteins that work against a gradient) require energy. why does active transport need energy
