Question

Is Bulk flow passive or active?

Answer 1

Bulk flow:

1. Active transport is the transport of molecules against their concentration gradient through the cell membrane by using the stored energy of the cells.
2. Passive transport is the movement of molecules from the concentrated area to their non-concentrated area without any use of energy from cells.
3. Bulk flow is the type of transport in bulk and transports large substances like lipids and food particles. It is an energy-consuming transport.
4. Hence, bulk flow is a means of active transport.
