What is the active transport and passive transport?

Answer 1

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 2

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 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

Active transport is the movement of particles across a cell membrane against their concentration gradient, requiring the input of energy, usually in the form of ATP. Passive transport, on the other hand, is the movement of particles along their concentration gradient, from an area of higher concentration to an area of lower concentration, without the need for energy input.

Answer 5

1) reverse gradient

2) input of chemical energy

3) molecule to perform active transport

Answer 6

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.
