1

Active transport

Able to move molecules against concentration gradient

2

No net movement

When solutions on either side of membrane are same concentration of water or solute

3

Turgor pressure in plants

Important in plants cells because as cells start to lose turgor pressure it wilts

4

Solute

The substance that is being dissolved in a solution

5

Carrier protein

Uses ATP to change shape to move molecules across cell membrane

6

Osmosis

Special type of diffusion where water is the moving substance

7

Hydrophobic

“Water fearing” - molecules that don’t mix well with charges or polar molecules

8

Isotonic

Refers to solution with same concentration when compared to another solution

9

Peripheral protein

Only passes part way through lipid bilayer of cell membrane

10

Active

Type of protein transport that requires ATP as an energy source

11

Gycolipid

A carbohydrate chain attached to lipid molecule in cell membrane

12

Hydrophilic

“Water loving” - molecules which mix well with charged or polar molecules

13

Concentration gradient

Rate of diffusion can be increased by increasing concentration gradient

14

Osmotic pressure

Occurs when there is a concentration gradient across a membrane and only water is able to pass through the membrane

15

Cell recognition protein

Has glycoproteins attached which are unique to each organisms and aid in immune system recognition

16

ATP

This molecule is the energy currency of the cell

17

Diffusion

Movement of molecules along a concentration gradient

18

Glycoprotein

A carbohydrate chain attached to a protein in the cell membrane

19

Endocytosis

Movement of a vacuole into the cell

20

Integral protein

Passes all the way through lipid bilayer of cell membrane

21

Hypertonic

Refers to solution that is more concentrated when compared to another solution

22

Passive

When movement of molecules don’t require additional energy input

23

Turgor pressure

If a plant cell is placed in a hypotonic solution, turgor pressure will develope

24

Channel protein

Allows a particular ion or molecule to pass through it with the concentration gradient and without ATP
