What is active transport and passive transport?

Answer 1

active transport requires the use of energy aka ATP and is usually against the concentration gradient.

passive transport does not require energy because it moves in response to the concentration gradient.

Answer 2

Active Transport

• Movement from Low Concentration to High Concentration
• ATP used
• Opposite diffusion

Passive transport

• Movement from High Concentration to Low Concentration
• No energy needed
• Is diffusion

Active Transport- When molecules move from an area of lower concentration to an area of higher concentration

Passive Transport- When molecules move form an area of higher concentration to an area of lower concentration (also called diffusion)

Active transport is the movement through a cell membrane using energy, an example is the movement from low to high concentration. In active transport transport proteins pick up molecules and carry them. Passive transport is the movement of materials through a cell membrane without the use of energy. Examples of this are diffusion and osmosis which move form low to high concentration.

Answer 3

passive transport is the movement of substance across a cell membrane along the concentration gradient.. which means from a higher concentration to a lower concentration without any energy expenditure.

active transport is movement of substance across a cell membrane against the concentration gradient with d expenditure of energy

Answer 4

Active transport is the movement of molecules across a cell membrane that requires energy in the form of ATP. Passive transport, on the other hand, is the movement of molecules across a cell membrane that does not require energy and occurs down a concentration gradient.

Answer 5

Passive transport. Diffuse of substance across the membrane with no energy investment.

Active transport. Uses energy to move solutes (substances) against their gradients.
