What is the active transport and passive transport?

Answer 1

Active transport is the movement of a substance across a cell membrane against its concentration gradient and Passive transport means moving biochemicals and other atomic or molecular substances across membranes.

Answer 2

The requirements of passive transport through the cell membrane (phospholipid bilayer) of an animal cell are that the molecule is non-polar or small enough to pass by the non-polar phospholipid tails. This is because, for there to be passive transport, no energy must be used to transport the molecule from outside of the cell to inside.

Answer 3

Energy is required in Active Transports. The reason why it needs energy is because you can see that active means busy and when someone is busy they use/build energy so that can remind you what is required in Active Transports.

NO energy is needed in Passive Transports.

Answer 4

1) reverse gradient

2) input of chemical energy

3) molecule to perform active transport

Answer 5

Energy in the form of ATP is required for active transport because it is moving substances in the opposite direction in which they would normally go.
