This is likely the source of your confusion. Bulk transport involves moving large particles or large amounts of material. Even if the movement is technically from high to low, because it involves the cell membrane physically moving and changing shape.
✅ So if you see “active transport high to low” – that’s actually . High to low is passive. active transport high to low
However, there are specific exceptions (like bulk transport) and nuances where energy is used to move things out of a cell. This is likely the source of your confusion
Cells create these "high to low" imbalances for several critical reasons: active transport high to low
