Transport Across Cell Membrane-> Kep Words

Question 1

Active transport

Answer 1

The transport of molecules agains their concentration gradient.
Low concentration to high concentration

Question 2

Cell membrane

Answer 2

“Selectively permeable membrane” controlling the entry and exit of materials

Question 3

Concentration gradient

Answer 3

The difference in concentration between two solutions, between different cells and surrounding solution.

Question 4

Diffusion

Answer 4

The net movement of molecule from an area of high concentration to low concentration

Question 5

Osmosis

Answer 5

The movement of water molecules across a partially permeable membrane.
Low solute concentration to a high salute concentration

Question 6
